[COMMON] Fix postgres data persistence
This changes fixes postgres data lost that occurs when postgres pods
are restarting.
When crunchy data postgres image starts, it runs /opt/cpm/bin/setenv.sh
script to set PGDATA folder. This script contains:
--
export PGDATA=/pgdata/$HOSTNAME
if [[ -v PGDATA_PATH_OVERRIDE ]]; then
export PGDATA=/pgdata/$PGDATA_PATH_OVERRIDE
fi
--
Since postgres is now a deployment (commit
0b243b600), its pod name is
different on each startup, hence HOSTNAME and PGDATA are also
different each time.
This change is leveraging crunchy data PGDATA_PATH_OVERRIDE environment
variable to set PGDATA to a fixed path. By default, this path is set to
/pgdata/data.
