Add workaround for pg_depend bug in PG < 15.4

PostgreSQL versions prior to 15.4 didn't properly update object
dependencies when setting a new access method on a table. The fix for
the bug is found in this commit:

postgres/postgres@97d8910

The `hypercore_create` test failed on buggy PG versions (e.g., 15.0)
due to wrong contents of pg_depend showing up in test output when
converting a table from Hypercore TAM back to regular heap.

This change adds a workaround that updates pg_depend with the correct
information when compiling against PG versions that suffer from the
bug.
