On Debian/Ubuntu, the default behavior is to have SSL enabled out
of the box, including for TCP connections to localhost.
That may be a good idea for remote access, but for local/LAN connections,
it can slow things down quite significantly . The problem is that people end
up using SSL without needing or knowing it.
Of course it can be turned off by using hostnossl for specific hosts in
pg_hba.conf, or globally with SSL=off in postgresql.conf, or using Unix
domain sockets for local connections, but people not well-versed in PG are
often not aware of this.
Other than that, the rest of the packaging is awesome, especially the layer
that make it possible to manage several simultaneous PG instances.
