Identifier max length

Hi, Certainly a stupid question : What is the max length for
identifiers. A test shows me 63 for a table name. I just
imagine it's the same for constraint name, view name etc ...
but I'm not sure. Or where can I get this info, because it's
not in the Postgresl docs ! Thanks

Yep, all 63 limit. Not sure where it is documented.
