Hi Shubham,
Here are few comments for 040_pg_createsubscriber.pl
1)
+# Run pg_createsubscriber on node S using '--cleanup-existing-publications'.
+# --verbose is used twice to show more information.
1a) /node S/ node S1
1b) Also, can we keep the comment in the same pattern as it was earlier -
# Run pg_createsubscriber on node S1. --verbose is used twice
# to show more information.
# In passing, also test the --enable-two-phase and
--cleanup-existing-publications
# options.
2)
+# Reuse P as primary
+# Set up node S2 as standby linking to node P
+$node_p->backup('backup_3');
/Reuse P as/ Reuse node P as/
3)
+$node_s2->append_conf(
+ 'postgresql.conf', qq[
+ primary_conninfo = '$pconnstr'
+ hot_standby_feedback = on
+ max_logical_replication_workers = 5
+ ]);
Do we need "hot_standby_feedback = on" on node_s2? I think we can remove it.
4)
+# Create user-defined publications
+$node_p->safe_psql($db3, "CREATE PUBLICATION test_pub3 FOR ALL TABLES;");
+$node_p->safe_psql($db3, "CREATE PUBLICATION test_pub4 FOR ALL TABLES;");
Can create both publications under one safe_psql as -
$node_p->safe_psql($db3, qq[CREATE PUBLICATION test_pub3 FOR ALL TABLES;
CREATE PUBLICATION test_pub4 FOR ALL TABLES;
]);
5)
+# Run pg_createsubscriber on node A without using
+# '--cleanup-existing-publications'.
+# --verbose is used twice to show more information.
5a) /node A/node S2/
5b) /without using '--cleanup-existing-publications' / without
'--cleanup-existing-publications' option
6)
+ ],
+ 'run pg_createsubscriber without --cleanup-existing-publications on node A'
+);
/node A/node S2/
7)
+# Drop the newly created publications
+$node_p->safe_psql($db3, "DROP PUBLICATION IF EXISTS test_pub3;");
+$node_p->safe_psql($db3, "DROP PUBLICATION IF EXISTS test_pub4;");
Similar to #4, use single safe_psql to drop both the publications.
OTOH, do we really need to drop the publications here? I think we can
remove this part since we're performing cleanup right after.
