Add PK constraint to a Unique Index via updating system catalogs? - Mailing list pgsql-general

Hi All;

We have a few very large tables with unique indexes on a column but the
column is not defined as the Primary Key.  Can we add a PK constraint
via updates to the system catalogs so we can avoid the lengthy checks
that would take place if we ran "alter table add constraint primary key...."


Thanks in advance
