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.

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.
Thanks for ideas/suggestion in Advance !!
