must be stale. Tweak example startup scripts to not use pg_ctl but launch
the postmaster directly, thereby ensuring that only the postmaster's direct
parent shell will be a postgres-owned process. In combination these should
fix the longstanding problem of the postmaster sometimes refusing to start
during reboot because it thinks the old lockfile is not stale.
subsequent core dump. It looks like at one time DBLINK_RES_ERROR_AS_NOTICE
didn't include a PQclear, but now it does and so these other ones are
duplicate.
mode see a fresh snapshot for each command in the function, rather than
using the latest interactive command's snapshot. Also, suppress fresh
snapshots as well as CommandCounterIncrement inside STABLE and IMMUTABLE
functions, instead using the snapshot taken for the most closely nested
regular query. (This behavior is only sane for read-only functions, so
the patch also enforces that such functions contain only SELECT commands.)
As per my proposal of 6-Sep-2004; I note that I floated essentially the
same proposal on 19-Jun-2002, but that discussion tailed off without any
action. Since 8.0 seems like the right place to be taking possibly
nontrivial backwards compatibility hits, let's get it done now.
-It fixes up some bugs with handling setval calls
-Adds upgrade instructions from prior versions
-Improved the sample config file
-Fixed some things in the clean_pending script
tablespaces correctly, and is quite restricted on objects covered (only
tables and databases, but not tablespaces and indexes).
The attached patch contributes:
- database_size(name)
- relation_size(text)
These are the well-known functions, tablespace-aware.
- pg_tablespace_size(oid)
- pg_database_size(oid)
- pg_relation_size(oid)
Tablespace-aware implementations, used by the upper functions.
pg_relation_size will report sizes of indexes as well.
- pg_size_pretty(bigint)
Formatting of sizes, to display '146MB' instead of '152885668'

PROCLOCK structs in shared memory now have only a bitmask for held
locks, rather than counts (making them 40 bytes smaller, which is a
good thing). Multiple locks within a transaction are counted in the
local hash table instead, and we have provision for tracking which
ResourceOwner each count belongs to. Solves recently reported problem
with memory leakage within long transactions.

as it stands - it mixes declarations in code, C++-style. The attached
patch shifts declarations to the tops of functions and enables this file
to compile cleanly as C.

keep track of portal-related resources separately from transaction-related
resources. This allows cursors to work in a somewhat sane fashion with
nested transactions. For now, cursor behavior is non-subtransactional,
that is a cursor's state does not roll back if you abort a subtransaction
that fetched from the cursor. We might want to change that later.
an empty input string causes an empty output string to be returned, instead of
throwing an ERROR -- per complaint from Aaron Hillegass, and consistent with
double metaphone. Fix examples in README.soundex pointed out by James Robinson.
performance front, but with feature freeze upon us I think it's time to
drive a stake in the ground and say that this will be in 7.5.
