process of dropping roles by dropping objects owned by them and privileges
granted to them, or giving the owned objects to someone else, through the
use of the data stored in the new pg_shdepend catalog.
Some refactoring of the GRANT/REVOKE code was needed, as well as ALTER OWNER
code. Further cleanup of code duplication in the GRANT code seems necessary.
Implemented by me after an idea from Tom Lane, who also provided various kind
of implementation advice.
Regression tests pass. Some tests for the new functionality are also added,
as well as rudimentary documentation.
the array (for array_push) or higher-dimensional array (for array_cat)
rather than decrementing it as before. This avoids generating lower
bounds other than one for any array operation within the SQL spec. Per
recent discussion.
Interestingly, this seems to have been the original behavior, because
while updating the docs I noticed that a large fraction of relevant
examples were *wrong* for the old behavior and are now right. Is it
worth correcting this in the back-branch docs?
functionality, but I still need to make another pass looking at places
that incidentally use arrays (such as ACL manipulation) to make sure they
are null-safe. Contrib needs work too.
I have not changed the behaviors that are still under discussion about
array comparison and what to do with lower bounds.

However, a patch has emerged (thanks, Seneca!) that does allow it to
work, and which I'd expect to be portable (better still!).
We are still actively pursuing why it breaks, but supposing that still
remains outstanding, at least the following would allow AIX users to
better survive a build...

useful to do so. This partially reverts an ill-considered search and
replace from a few months ago.

inFromCl true, meaning that they will list out as explicit RTEs if they
are in a view or rule. Update comments about inFromCl to reflect the way
it's now actually used. Per recent discussion.
