you need to DROP the database you removed, then re-create it as a new
empty database. You cannot re-join a node that has been removed.
postgres=# DROP DATABASE bdrdemo;
ERROR: database "bdrdemo" is being accessed by other users
DETAIL: There is 1 other session using the database.
Something's holding it open, not sure exactly what.
More specifically, it seems like it's the bgworker that's holding that
DB:
1123 ? S 0:00 /usr/lib/postgresql/9.4/bin/postgres -D
/var/lib/postgresql/9.4/main -c
config_file=/etc/postgresql/9.4/main/postgresql.conf
1124 ? Ss 0:00 \_ postgres: logger process
1126 ? Ss 0:00 \_ postgres: checkpointer process
1127 ? Ss 0:00 \_ postgres: writer process
1128 ? Ss 0:00 \_ postgres: wal writer process
1129 ? Ss 0:00 \_ postgres: autovacuum launcher process
1130 ? Ss 0:00 \_ postgres: stats collector process
1136 ? Ss 0:00 \_ postgres: bgworker: bdr supervisor
1137 ? Ss 0:00 \_ postgres: bgworker: bdr db: bdrdemo
Should I just kill that process, or is there a "nicer" way to do it?
More generally, is there a way to just turn off BDR entirely on one
node? I can't find a clear answer in the documentation to questions like
- how do I turn on or off replication altogether?
