Description

I have a unique constraint on a col, and ddltuils tries to drop it like its only an index, which gives an error:

[sql] Failed to execute: DROP INDEX fields_name_type_unq

BUILD FAILED
C:\mchyzer\isc\dev\grouper-qs-1.2.0\grouper\build.xml:769: org.postgresql.util.PSQLException: ERROR: cannot drop index fields_name_type_unq because constraint fields_name_type_unq on table grouper_fields requires it

The solution would be to look at db metadata, see that it is a constraint, drop the constraint, then drop the index (if it isnt dropped by dropping the constraint)

Thanks,
chris
