generation_counter includes time spent on both JIT:ing expressions
and tuple deforming which are configured independently via options
jit_expressions and jit_tuple_deforming. As they are combined in
the same counter it's not apparent what fraction of time the tuple
deforming takes.
This adds deform_counter dedicated to tuple deforming, which allows
seeing more directly the influence jit_tuple_deforming is having on
the query. The counter is exposed in EXPLAIN and pg_stat_statements
bumpin pg_stat_statements to 1.11.

This commit allows specifying a --sync-method in several frontend
utilities that must synchronize many files to disk (initdb,
pg_basebackup, pg_checksums, pg_dump, pg_rewind, and pg_upgrade).
On Linux, users can specify "syncfs" to synchronize the relevant
file systems instead of calling fsync() for every single file. In
many cases, using syncfs() is much faster.
As with recovery_init_sync_method, this new option comes with some
caveats. The descriptions of these caveats have been moved to a
new appendix section in the documentation.

When running a repeat query with \watch in psql, it can be
helpful to be able to stop the watch process when the query
no longer returns the expected amount of rows. An example
would be to watch for the presence of a certain event in
pg_stat_activity and stopping when the event is no longer
present, or to watch an index creation and stop when the
index is created.
This adds a min_rows=MIN parameter to \watch which can be
set to a non-negative integer, and the watch query will
stop executing when it returns less than MIN rows.

We now create contype='n' pg_constraint rows for not-null constraints.
We propagate these constraints to other tables during operations such as
adding inheritance relationships, creating and attaching partitions and
creating tables LIKE other tables. We also spawn not-null constraints
for inheritance child tables when their parents have primary keys.
These related constraints mostly follow the well-known rules of
conislocal and coninhcount that we have for CHECK constraints, with some
adaptations: for example, as opposed to CHECK constraints, we don't
match not-null ones by name when descending a hierarchy to alter it,
instead matching by column name that they apply to. This means we don't
require the constraint names to be identical across a hierarchy.
For now, we omit them for system catalogs. Maybe this is worth
reconsidering. We don't support NOT VALID nor DEFERRABLE clauses
either; these can be added as separate features later (this patch is
already large and complicated enough.)
psql shows these constraints in \d+.
pg_dump requires some ad-hoc hacks, particularly when dumping a primary
key. We now create one "throwaway" not-null constraint for each column
in the PK together with the CREATE TABLE command, and once the PK is
created, all those throwaway constraints are removed. This avoids
having to check each tuple for nullness when the dump restores the
primary key creation.
pg_upgrading from an older release requires a somewhat brittle procedure
to create a constraint state that matches what would be created if the
database were being created fresh in Postgres 17. I have tested all the
scenarios I could think of, and it works correctly as far as I can tell,
but I could have neglected weird cases.
This patch has been very long in the making. The first patch was
written by Bernd Helmle in 2010 to add a new pg_constraint.contype value
('n'), which I (Álvaro) then hijacked in 2011 and 2012, until that one
was killed by the realization that we ought to use contype='c' instead:
manufactured CHECK constraints. However, later SQL standard
development, as well as nonobvious emergent properties of that design
(mostly, failure to distinguish them from "normal" CHECK constraints as
well as the performance implication of having to test the CHECK
expression) led us to reconsider this choice, so now the current
implementation uses contype='n' again. During Postgres 16 this had
already been introduced by commit e056c557aef4, but there were some
problems mainly with the pg_upgrade procedure that couldn't be fixed in
reasonable time, so it was reverted.
In 2016 Vitaly Burovoy also worked on this feature[1] but found no
consensus for his proposed approach, which was claimed to be closer to
the letter of the standard, requiring an additional pg_attribute column
to track the OID of the not-null constraint for that column.

The source code comment already said that the presence of the field
element_types.domain_default might be a bug in the standard, since it
never made sense there. Indeed, the field is gone in newer versions
of the standard. So just remove it.
This was disabled in commit 6f80a8d9c due to the lack of support for
handling of pseudoconstant quals assigned to replaced joins in
createplan.c. To re-allow it, this patch adds the support by 1)
modifying the ForeignPath and CustomPath structs so that if they
represent foreign and custom scans replacing a join with a scan, they
store the list of RestrictInfo nodes to apply to the join, as in
JoinPaths, and by 2) modifying create_scan_plan() in createplan.c so
that it uses that list in that case, instead of the baserestrictinfo
list, to get pseudoconstant quals assigned to the join, as mentioned in
the commit message for that commit.
Important item for the release notes: this is non-backwards-compatible
since it modifies the ForeignPath and CustomPath structs, as mentioned
above, and changes the argument lists for FDW helper functions
create_foreignscan_path(), create_foreign_join_path(), and
create_foreign_upper_path().

Currently, the names of the custom wait event must be registered for
each backend, requiring all these to link to the shared memory area of
an extension, even if these are not loaded with
shared_preload_libraries.
This patch relaxes the constraints related to this infrastructure by
storing the wait events and their names in two dynamic hash tables in
shared memory. This has the advantage to simplify the registration of
custom wait events to a single routine call that returns an event ID
ready for consumption:
uint32 WaitEventExtensionNew(const char *wait_event_name);
The caller of this routine can then cache locally the ID returned, to be
used for pgstat_report_wait_start(), WaitLatch() or a similar routine.
The implementation uses two hash tables: one with a key based on the
event name to avoid duplicates and a second using the event ID as key
for event lookups, like on pg_stat_activity. These tables can hold a
minimum of 16 entries, and a maximum of 128 entries, which should be plenty
enough.
The code changes done in worker_spi show how things are simplified (most
of the code removed in this commit comes from there):
- worker_spi_init() is gone.
- No more shared memory hooks required (size requested and
initialization).
- The custom wait event ID is cached in the process that needs to set
it, with one single call to WaitEventExtensionNew() to retrieve it.
Per suggestion from Andres Freund.

Two backend routines are added to allow extension to allocate and define

"Extension":
* WaitEventExtensionNew(), that allocates a wait event ID computed from

* WaitEventExtensionRegisterName(), to associate a custom string to the
wait event ID allocated.
Note that this includes an example of how to use this new facility in
worker_spi with tests in TAP for various scenarios, and some
documentation about how to use them.
Any code in the tree that currently uses WAIT_EVENT_EXTENSION could

This commit switches the client-side data generation from INSERT queries
to COPY for the two tables pgbench_branches and pgbench_tellers.
pgbench_accounts was already using COPY.
COPY is a better interface for bulk loading or high latency connections
(this point can be countered with the option for server-side data
generation, still client-side is the default), and measurements have
proved that using it for these two other tables can lead to improvements
during initialization. I did not notice slowdowns at large scale
numbers on a local setup, either, most of the work happening for the
accounts table.
Previously COPY was only used for the pgbench_accounts table because the
amount of data was much larger than the two other tables. The code is
refactored so as all three tables use the same code path to execute the
COPY queries, with a callback to build data rows.

With the addition of INHERIT and SET options for role grants,
the historical display of role memberships in \du/\dg is woefully
inadequate. Besides those options, there are pre-existing
shortcomings that you can't see the ADMIN option nor the grantor.
To fix this, remove the "Member of" column from \du/\dg altogether
(making that output usefully narrower), and invent a new meta-command
"\drg" that is specifically for displaying role memberships. It
shows one row for each role granted to the selected role(s), with
the grant options and grantor.

Until now, when DROP DATABASE got interrupted in the wrong moment, the removal
of the pg_database row would also roll back, even though some irreversible
steps have already been taken. E.g. DropDatabaseBuffers() might have thrown
out dirty buffers, or files could have been unlinked. But we continued to
allow connections to such a corrupted database.
To fix this, mark databases invalid with an in-place update, just before
starting to perform irreversible steps. As we can't add a new column in the
back branches, we use pg_database.datconnlimit = -2 for this purpose.
An invalid database cannot be connected to anymore, but can still be
dropped.
Unfortunately we can't easily add output to psql's \l to indicate that some
database is invalid, it doesn't fit in any of the existing columns.
Add tests verifying that a interrupted DROP DATABASE is handled correctly in
