No, to_char understands numeric locales regardless of enable-nls.
There is no provision for locale-dependent output from a plain
numeric column; you must use to_char.
The to_char results I could see from my tests. I was thinking that
perhaps if NLS was enabled, numeric results in, for example, psql
would be displayed even without using to_char. However, I can't seem
to coax the server to give me results in that way. Perhaps I'm just
doing it wrong.

Just to clarify, I was thinking that perhaps the a_numeric column
would show a result of 1,23 since lc_numeric was set to es_ES. After
testing with --enable-nls, I see that's not the case.
