Hi Marc,
what happened with the patches at
http://docs.freevps.com/doku.php?id=3Dfre=
ebsd:changelog?
Those patches are supposed to make IPC run without collisions in many
jails=
, thus solving the
classic problem with postgresql, allowing the admin to use the same uid,
PG=
****T in all pgsql
server instances.
Do you know if any of this stuff make it anywhere in official FreeBSD?
