Re: Try catch error, return data

I think you're looking for EXCEPTION:

https://www.postgresql.org/docs/14/plpgsql-control-structures.html#PLPGSQL-ERROR-TRAPPING

At the point you've trapped the error, you can then return something based
on the error. You can find a list of exception codes in one of the
appendices:
