Subject: [PATCH] doc: Correct the documented type of
 pg_get_multixact_stats().num_mxids

The documentation listed num_mxids as integer, but its SQL type has
been bigint since the function was introduced. Correct the
documentation to match the actual return type.

Backpatch to v19, where the function was introduced.
