Correct. This is why most of them point out that they are not
act
time. Does that mean that
almost every part of postgres that interacts with memory or the Datum
type must be read very carefully to rediscover all the assumptions
behind the code? Unfortunately I would guess yes. This is going to
take much longer than I thought. But it's that or use MySQL, wh
not submitting it for inclusion yet. I'd like to
submit it first so that people can look over it.

In the code below, fld_size gets copied in from a user specified file.
It is passed as the 'needed' parameter to enlargeStringInfo(). If
needed is a very large positive value, the addition 'needed += str->len
+ 1;' could cause an overflow

This is the safest way. It prevents problems when $foo begins with with a

I think that it does solve the problem. The only drawback is that it's not

Already, Trond Eivind Glomsrød [EMAIL PROTECTED] has volunteered to test on

I don't have a machine with XFS installed and it will be at least a week

res, Mariposa, and Postgres 4.2.
There's also the Shore data manager. While not a complete SQL database,
I've wondered if it could actually be spliced into PostgreSQL, since the
licenses appear compatible.

Okay, you're right. I just updated my Ghostscript to 7.00 (just out) and it
produced very nice PDFs. I can upload them somewhere if you give me an FTP

The second parameter to "rtrim" is interpreted as a set of characters and
rtrim:
"Returns string with final characters removed after the last character not
in set"
So rtrim("center_out_opto", "_opto") returns
"center_ou"
because "u" is not in the set {o, p, t, _} but all the characters after

standard says?
It was even suggested to me on the linux-fsdev mailing list that mlock() was
a good way to insure the write-ahead condition.
