Thanks for the review!
I removed the above and added the following for that case.
+ /* Complete ALTER DATABASE|FUNCTION|ROLE|USER ... SET <name> */
+ else if (Matches2("ALTER", "DATABASE|FUNCTION|ROLE|USER") &&
+ TailMatches2("SET", MatchAny))
+ COMPLETE_WITH_LIST2("FROM CURRENT", "TO");
Attached is the updated version of the patch.
I also added the change that Sawada suggested, to the patch.
