Masahiko Sawada 8a2beb5f15 doc: Clarify phase descriptions of pg_stat_progress_repack.
The "initializing" phase was described as expected to be very brief,
but for REPACK (CONCURRENTLY), it also covers enabling and
initializing logical decoding, either of which can take a long
time. Also, the "catch-up" phase includes waiting for the ACCESS
EXCLUSIVE lock needed to swap the files, which was not mentioned.

Adding separate progress phases for these steps is left for v20; for
v19 we only clarify the description.
