 Priority:  medium                 |   Milestone:  PostGIS 2.0.0

-----------------------------------+----------------------------------------
 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.
