[Q] sequence and index name limits in 8.4
Searched docs and the web but only saw references to the older version
of postgres
where changing source code was recommended ( NAMEDATALEN) if more than
31 characters
in the names are desired.
wanted to ask if this is still the case in 8.4 (I need at least 128)
thank you in advance,
VSP

Unless you want to compile your own version, I think the curent limit
is 64 or 63 characters. There are real and measurable performance hits
as you go over that number.

Also, it hasn't been 32 by default since 7.2, more than seven years ago.
Whatever references you are reading are so out of date as to be
completely untrustworthy ...
