Thanks for updating the patch. Here are few comments:
1.
pg_log_error("object type \"%s\" is
specified more than once for --remove", optarg);
exit(1);
Consider using pg_fatal for simplicity.
2.
+ /* Fetch all publication names */
+ res = PQexec(conn, "SELECT pubname FROM
pg_catalog.pg_publication;");
+ if (PQresultStatus(res) != PGRES_TUPLES_OK)
+ {
+ pg_log_error("could not obtain publication information:
%s",
+ PQresultErrorMessage(res));
+ PQclear(res);
+ disconnect_database(conn, false);
+ return;
+ }
I think we should exit here for consistency, as performed in similar cases.
3.
+ pg_log_info("dropped all publications in database \"%s\"",
dbinfo->dbname);
This message may be misleading if some publications were not dropped
successfully, as drop_publication does not exit on a drop failure.
4.
if (opt.remove_objects.head != NULL)
{
for (SimpleStringListCell *cell = opt.remove_objects.head;
cell; cell = cell->next)
{
I think the first null test is redundant.
I have attached a patch with the proposed changes. If you agree with these
modifications, please merge them.
Best Regards,
