Hi Adrian,
I see nowhere in your init-master.sh where Postgres is restarted.
Yes, you're right. The base image takes care of that –– the base image
of mdillon/postgis is postgres:9.3. See here, for instance:
https://github.com/docker-library/postgres/blob/master/9.3/docker-entrypoint.sh#L70
When the startup command –– CMD in Docker lingo –– is "postgres" it does
a bunch of initialization operations, and then runs the user procided
scripts in the /docker-entrypoint-initdb.d directory.
Then finally it starts up the postgres process with /gosu postgres "$@".
/ The gosu is a wrapper that passes user commands to the end process,
i.e. postgres, and I'm not sure what $@ is but I think it's to give the
user a shell.
I do not have time to go through all the scripts, but wanna make a bet
that it is starting Postgres with a different set up conf files then you
think or a different instance of Postgres:)?
On your primary I would confirm what is actually run when all the
scripting is done. Also when the primary is running take a look at
http://www.postgresql.org/docs/9.3/static/monitoring-stats.html#PG-STAT-REPLICATION-VIEW
I am almost positive that somewhere in the switch from --single mode to
regular mode information is being lost.
