Re: implement CAST(expr AS type FORMAT 'template') - Mailing list pgsql-hackers

The latest patch fail make check in my testrun:

not ok 166   + collate.linux.utf8


+    if ((str == NULL || fmtisnull) && flinfo->fn_strict)
+        return (Datum) 0;        /* just return null result */

With the condition written like this a non strict formatter function
ignores nulls, and possibly crashes the server.


Shouldn't pg_dump also handle the new TYPEFORMAT_IN? Currently it's
lost during a dump-restore.
