Hello
I have class MSG with a bytea (variable length array of bytes) field, and
I need to add instances to it trough a C source code using LIBPQ functions.
This field can contain zero values, and I don't know how to build a query
string, to use in PQexec, that doesn't finish when a zero value occours in
some position (not the last) of this field.
Can anyone help me?

the base variable-length types (bytea, text) are implemented in
src/backend/utils/adt/varlena.c.
it looks like bytea takes constants of the form \xxx where xxx is an
octal constant and must have exactly three digits.

* NetBSD 1.0 port

Hi Everyone,
I started a port of postgres 4.2 for NetBSD 1.0 about a month ago.
I made good progress the first week and I was able to get the system
to build to completion. While running the regression tests I found
that my port, taken from the Postgres 4.01 NetBSD port, of the dynamic
loader fails to load objects correctly. I haven't had the chance
to look into this problem for a number of weeks now. I plan to
complete the port in the next few days. To avoid reinventing the wheel,
and to save me some headachs, I thought I would check if anyone else
has done this, or am I treading new territory.
Any help is appreciated.
Thanks,
Jim Bachesta
