Please add "IF EXIST" to recreatedb.sh script

https://github.com/metabrainz/musicbrainz-docker/blob/master/build/musicbrainz/scripts/recreatedb.sh

It throws an error, if the DB does not exist.
Could you please change the line
psql postgres -U musicbrainz -h db -c "DROP DATABASE musicbrainz_db;"; createdb.sh "$@"
into
psql postgres -U musicbrainz -h db -c "DROP DATABASE IF EXISTS musicbrainz_db;"; createdb.sh "$@"
according to https://www.postgresql.org/docs/current/sql-dropdatabase.html

This would allow to use recreatedb.sh in any case.
If the DB does not exist, it does not stop working with an error:

ERRROR:  database "musicbrainz_db" does not exist
ERROR: 1

If the DB does exist, it will be dropped/deleted and then - inside the script createdb.sh - newly created.

Thank you for pointing this out, it’s likely an oversight. Change made in commit 2317ebf. It will be part of today’s release.
