You have to disable triggers. Two options: - Export table data, truncate table (if your table is fk source you will have a problem), add constraint and import exported data with --disable-triggers flag in pg_restore. - Perhaps you could add manually triger via pg_trigger table in pg_catalog whith an insert into this table. -----Original Message----- From: Amit jain <amitjain@xxxxxxxxxxxxx> To: pgsql-admin@xxxxxxxxxxxxxx <pgsql-admin@xxxxxxxxxxxxxx> Subject: How to add constraints without validating data. Date: Thu, 27 May 2010 17:55:56 +0530 Hi Gurus Is there any way in postgreSQL to apply constraints forcefully without checking/validating Data ? It should validate only those records which comes after constraints are applied. I need this help as data is already loaded in database but "ALTER TABLE" sql for adding CONSTRAINTS is taking enormous time.
