Hi folks, As discussed on -hackers , here is a patch to add a pg_typeof() builtin function to core.
The function accepts one argument (type "any") and returns the regtype of that argument. This can be helpful in various circumstances, including troubleshooting cast/coercion behaviour in a query, or constructing dynamic SQL statements. It's declared in builtins.h and defined in utils/adt/misc.c. The patch includes a small documentation update; I added pg_typeof() to Table 9-47. System Catalog Information Functions, and a brief descriptive paragraph underneath the table. This didn't seem like it warranted any additional regression tests. Added to the November commitfest.
