Explicit type signatures fail to parse

[nikita-volkov]

E.g.,

> parseQueryExpr defaultParseFlags "" Nothing "select 'a' :: text"
Left (line 1, column 12):
unexpected (("",1,12),Symbol ":")
expecting operator or end of input
cannot make functioncall from StringLit (Annotation {anSrc = Just ("",1,8), anType = Nothing, anErrs = [], anImplicitCast = Nothing, anCatUpd = []}) "a"
:1:12:

Context:
select 'a' :: text
           ^
      ERROR HERE

Does it work if you use the postgresDialect in the parse flags? The default dialect is ANSI which doesn't support this syntax for casts. The dialect support is a bit flakey at the moment.

Already moved on to another solution. Sorry
