Ticket #1704 (closed defect: fixed)
Change uninstall generators do DROP AGGREGATE IF EXISTS
|Reported by:||robe||Owned by:||strk|
DROP AGGREGATE IF EXISTS has existed since PostgreSQL 8.2, so there is no reason not to use it.
As noted in #1693, changing the uninstall to DROP AGGREGATE IF EXISTS will make uninstall_legacy work for both legacy and legacy_minimal. It will help for the other uninstall scripts as well.
