postgres on notebook

Silly question,

I've got nice ThinkPad 390E with 128Mb RAM and install Linux+Postgres
6.5.3. Everything work like a charm except strange behaivour when
notebook wake up after suspend mode. I noticed
a lot of [postmaster] in ps output. Is it normal ?
Usually I see like now:
4513 ? S 0:00 /usr/local/pgsql/bin/postmaster -i -B 1024 -N 32 -S -
4941 ? S 0:00 /usr/local/pgsql/bin/postgres localhost httpd discove
4943 ? S 0:00 /usr/local/pgsql/bin/postgres localhost httpd polit_d
4944 ? S 0:00 /usr/local/pgsql/bin/postgres localhost httpd voting
4945 ? S 0:00 /usr/local/pgsql/bin/postgres localhost httpd discove
4946 ? S 0:00 /usr/local/pgsql/bin/postgres localhost httpd polit_d
4947 ? S 0:00 /usr/local/pgsql/bin/postgres localhost httpd voting
4948 ? S 0:00 /usr/local/pgsql/bin/postgres localhost httpd discove
4949 ? S 0:00 /usr/local/pgsql/bin/postgres localhost httpd polit_d
4950 ? S 0:00 /usr/local/pgsql/bin/postgres localhost httpd voting

I have apache+modperl running with persistent connection with postgres using
DBI/Apache::DBI. After wake up, all these stuff seems work ok,
but probably [postmaster] processes doesn't works, at least I've seen
new postgres processes with much more PID's appearing (Apache::DBI should
take care about that). I didn't take much attention yet and just asking
if there are something special with Postgres interaction with
Linux running on notebook (apm stuff)

Regards,

Oleg
