This change fixes Citus metadata sync issues where nodes register in
pg_dist_node with ephemeral pod IPs. When pods restart and get new IPs,
the stale IPs in pg_dist_node cause metadata synchronization to fail.
Changes:
- PatroniConfigMap.java: Added PATRONI_CONFIG_SERVICE_NAME and
PATRONI_POD_NAMESPACE env vars, changed PATRONI_POSTGRESQL_CONNECT_ADDRESS
to use FQDN pattern
- PatroniEnvironmentVariables.java: Changed PATRONI_RESTAPI_CONNECT_ADDRESS
to use FQDN pattern
- start-patroni.sh: Changed connect_address in restapi and postgresql
sections to use the FQDN-based env vars instead of PATRONI_KUBERNETES_POD_IP
The FQDN pattern used is:
${POD_NAME}.${PATRONI_CONFIG_SERVICE_NAME}.${PATRONI_POD_NAMESPACE}.svc.cluster.local
This ensures stable node registration that survives pod restarts.
