The \d+ command attempts to print out any publications that the relation
is part of. To find the publications it is part of, it runs this query:
"SELECT pub.pubname\n"
" FROM pg_catalog.pg_publication pub,\n"
" pg_catalog.pg_get_publication_tables(pub.pubname)\n"
"WHERE relid = '%s'\n"
"ORDER BY 1;",
pg_get_publication_tables() calls GetPublicationByName(), which throws
this error.
So I suppose that if a publication is dropped between the time
pg_publication is read and the function is called, you could get this error.
How could we improve that?
