Add call to object access hook at the end of table rewrite in ALTER TABLE
ALTER TABLE .. SET {LOGGED,UNLOGGED,ACCESS METHOD} would never do a
table-level object access hook, which was inconsistent with SET
TABLESPACE. Note that contrary to SET TABLESPACE, the no-op case is
left off for those commands as this requires tracking if commands have
been called, but they may not execute a physical rewrite. Another thing
worth noting is that the physical file swap at the end of a rewrite
does a couple of access calls for internal objects created for the swap
operation (internal objects are for example skipped by the tests of
sepgsql), but this does not trigger the hook for the table on which the
operation is done.
f41872d, that added support for SET LOGGED/UNLOGGED in ALTER TABLE,
visibly forgot to consider that.
Based on what I checked, two regression tests of sepgsql in ddl.sql are
going to log more information with this test, something that buildfarm
member rhinoceros will tell soon enough. I am not completely sure of
their format though, so these are not refreshed yet.
This is arguably a bug, but no backpatch is done as this could cause a
behavior change for anybody using object access hooks.
