Обсуждение: CREATE FUNCTION

Hello:

I found that when I use CREATE FUNCTION in postgresql, the maximum number of
arguments is 16 only. How I config so that the CREATE FUNCTION allows
unlimited number of arguments?

Thanks a lot!
Carmen

Change FUNC_MAX_ARGS in src/include/pg_config.h, 'make clean',
recompile, re-install, and re-initdb.

Cheers,

Check the mailing archives - there's a constant in pg_config.h you'll need to
increase and then recompile. Don't forget to dump your database first for
backup.

Is the initdb really necessary? Will the modified postmaster not work on
the existing data directory?

Yes.
