Heikki Linnakangas 7afca7edef Relax assertion in finding correct GiST parent Commit `28d3c2ddcf` introduced an assertion that if the memorized downlink location in the insertion stack isn't valid, the parent's LSN should've changed too. Turns out that was too strict. In gistFindCorrectParent(), if we walk right, we update the parent's block number and clear its memorized 'downlinkoffnum'. That triggered the assertion on next call to gistFindCorrectParent(), if the parent needed to be split too. Relax the assertion, so that it's OK if downlinkOffnum is InvalidOffsetNumber. Backpatch to v13-, all supported versions. The assertion was added in commit `28d3c2ddcf` in v12.

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.

General documentation about this version of PostgreSQL can be found at https://www.postgresql.org/docs/devel/. In particular, information about building PostgreSQL from the source code can be found at https://www.postgresql.org/docs/devel/installation.html.
