Are there any professional fulltime PostgreSQL DBA's? For my job I work on a JavaEE application with PostgreSQL as the database. Although we have a sysadmin for our productions servers, who also manages our database servers, we have no full-time DBA which makes me wonder if there are any. I would imagine any full-time dedicated DBA would work exclusively with Oracle database. Am I overlooking something or am I correct in assuming that there are no dedicated Postgres DBA's? 

PS: I'm just asking this out of sheer curiosity. 

PPS: I wanted to tag this question with DBA but apparently that would be a new tag. Could someone make this for me?
Judging from the activity on the PostgreSQL jobs mailing list I'd say it's not all that uncommon to find full-time PostgreSQL DBAs.
