If a new database is created on the primary server while
pg_createsubscriber is running, the subscription will not be created
for the new database.
To reproduce this issue, follow these steps:
Debug pg_createsubscriber and set a breakpoint after the
fetch_source_databases function, where the databases would have been
prepared.
While execution of pg_createsubscriber is paused, create a new
database on the primary node.
You will observe that the database is created on the standby node, but
the subscription will not be created for the newly created database.
+fetch_source_databases(struct CreateSubscriberOptions *opt)
+{
+ PGconn *conn;
+ PGresult *res;
+ int num_rows;
+
+ /* Establish a connection to the PostgreSQL server */
+ conn = connect_database(opt->pub_conninfo_str, true);
+
+ res = PQexec(conn, "SELECT datname FROM pg_database WHERE
datistemplate = false AND datallowconn = true");
+
+ /* Check for errors during query execution */
+ if (PQresultStatus(res) != PGRES_TUPLES_OK)
