Dear John, Thanks for sharing solution approaches. >do each reindex as a seperate transaction so only one table gets locked at a time. Transaction is already in separate like REINDEX TABLE table1, REINDEX TABLE table2 etc.. But this problem is occurred. One more question regarding below. alter table table1 add constraint fk_key foreign key (id, roll_number) references table2 (id, roll_number) on delete restrict on update restrict; It shows below error: ERROR: there is no unique constraint matching given keys for referenced table "table2" Table1 contains below structure: create table table1 ( id char(6) not null, roll_number varchar(20) not null, ----- primary key (id, roll_number) Table2 contains below structure: create table table2 ( id char(6) not null, roll_number varchar(20) not null, account_id varchar(20) not null default '-', ----- primary key (id, roll_number, account_id) How to resolve this issue?
