Add the 'checkunique' argument to bt_index_check() and bt_index_parent_check(). When the flag is specified the procedures will check the unique constraint violation for unique indexes. Only one heap entry for all equal keys in the index should be visible (including posting list entries). Report an error otherwise. pg_amcheck called with the --checkunique option will do the same check for all the indexes it checks.

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download/ See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions.
