That's what I did.  Way back in the days of pg 6.5 I helped build a
corporate intranet and as the senior architect of all of it, I had to
learn both how to admin unix boxes and keep a postgres db happy.  I
later learned other dbs (Oracle, db2, and a few others) because we
were constantly interacting with them as the corporate intranet
system.

While it's common for dbas to specialize a lot on dbs like Oracle
(just performance, or development, or 24/7 operation and so on) most
pgsql dbas are, by necessity, generalists.  Management often hires a
large team for a database with $500,000 in licensing without batting
an eye, but when the db is free, figure they can get by with 1 or 2
DBAs max.
