Re: Simple queries with JDBC escaped scalar functions result in exceptions

I upgraded to postgresql-9.4.1209.jar and fixed all the places in our code that used JDBC escaped scalar functions (e.g., {fn now()}) inside function definitions. However, we continued to see the telltale exception (org.postgresql.util.PSQLException: ERROR: syntax error at or near "{") when executing straightforward SELECT queries that included scalar functions. I tracked this down to comments; a simple repro is to execute the following query via JDBC:

SELECT /* $ */ {fn curdate()}

The original comments included many characters, but the dollar sign seems to be the culprit. I think this indicates a problem with the parser that's attempting to detect string literals.

Thanks,
