pg_repack needs to take an exclusive lock at the end of the
reorganization. If the lock cannot be taken after duration
--wait-timeout option specified and this option is true,
pg_repack gives up to repack a target table instead of
cancelling conflicting backend. False by default.
During repacking table, if a transaction executes INSERT CONFLICT
ON UPDATE/DO NOTHING, because we define BEFORE trigger on target
table, the contents of operation log table becomes inconsistent
easliy. As a result, pg_reapck fails with a high probability.
To resolve this issue, this changes the trigger type from BEFORE
to AFTER. We define AFTER trigger that is the first of the AFTER
trigger to fire on the table.
Adds support for repacking only the tables in a specified schema. This
doesn't support --only-indexes mode, but that seems alright for now.
Fix merge conflicts, and make a few tweaks along the way:
* bump version to 1.3-dev0
* add Beena to list of maintainers
* documentation wordsmithing
* fix up the INFO message printed for each index in --index or
--only-indexes mode, so that it is only printed once per index, and
prints the name of the original index, not that of the transient
index_%u name.
It was possible to specify both --schema and --table which probably
-should- be legal but would need some code to be rewritten. This patch
adds a check that both can't be specified and returns an error telling
the user to use schema.table notation instead. A regression test
checking this behaviour was added.
