Sorry, the comment above was not correct.
The fix was about pasl's \d meta-command, not tab-complement.

-			if (tableinfo.relpersistence == 'u')
-				printfPQExpBuffer(&title, _("Unlogged materialized view \"%s.%s\""),
-								  schemaname, relationname);
-			else
-				printfPQExpBuffer(&title, _("Materialized view \"%s.%s\""),
-								  schemaname, relationname);
+			printfPQExpBuffer(&title, _("Materialized view \"%s.%s\""),
+

"Unlogged materialized view" is never printed since it cannot be created from the beginning
of materialized view support, so this is a dead code to be removed.
