Subject: How to workaround DROP CONSTRAINT [ IF EXISTS ] in Postgres version 8.1?
Date: Wed, 2 Feb 2011 14:21:43 -0800 (PST)
Message-ID: <1296685303841-3368570.post@n5.nabble.com> (raw)


Hello,


I found that DROP CONSTRAINT [ IF EXISTS ] is available in Postgres 9.1
http://developer.postgresql.org/pgdocs/postgres/sql-altertable.html
http://developer.postgresql.org/pgdocs/postgres/sql-altertable.html


But it is not avaiable in Postgres 8.1
http://www.postgresql.org/docs/8.1/interactive/sql-altertable.html
http://www.postgresql.org/docs/8.1/interactive/sql-altertable.html


Is there a way to achieve this on Postgres 8.1?

Thanks a lot
