why do you use EXEC there do only BEGIN IF EXISTS(SELECT * FROM information_schema.schemata WHERE schema_name = 'secc_master'_ THEN ... ELSE ... END IF; > > IF i THEN > > return i; > else > > return i; > end if; > > end; > $BODY$ > LANGUAGE plpgsql > > ERROR: column "secc_master" does not exist > LINE 1: ...M information_schema.schemata WHERE schema_name = secc_maste... you have to use quote_literal function there, not quote_ident.
