Worker crashes when use `IS NOT NULL` for `TIMESTAMP` type.

Bug description

As @gibber9809 mentioned:
This maybe related to y-scope/clp#1096 tbh
Or rather it is related -- the pass currently makes assumptions that you're trying to compare timestamps against literals that can be interpreted as timestamps
Pretty much just need to add some special cases in that pass for when the literal is a wildcard, for when the literal otherwise can't be interpreted as a timestamp, and for when there is no literal (e.g. because it is doing an operation like EXISTS/NEXISTS which doesn't have an associated literal).
