Probably not much help but it seems to work ok for me (unless I'm doing something stupid). You didn't actually say how/where you were doing the regex match, but the '~' operator seems to work ok.

Hi All
Got a weird one. I am using the regex below to case match numeric only values.
'^([0-9]+[.]?[0-9]*)$'
This works well by and large but not for a value like “1234:567”. This seems to match positive and then fails due to not being an actual number in the subsequent cast.
Any ideas? (PG13)
