Alexander Korotkov cdf1f5a607 Reintroduce test 046_checkpoint_logical_slot
This commit is only for HEAD and v18, where the test has been removed.
It also incorporates improvements below to stability and coverage of the
original test, which were already backpatched to v17.
- Add one pg_logical_emit_message() call to force the creation of a record
  that spawns across two pages.
- Make the logic wait for the checkpoint completion.

This directory contains a variety of test infrastructure as well as some of the

individual contrib/ modules and in src/bin.

Not all these tests get run by "make check". Check src/test/Makefile to see
which tests get run automatically.

  "make check"

  for installing in production databases
