Entered portage in 08 May 2012 and has no open bug report, works just fine at least for me, even with jdk:1.7
This tripped me up as well. Postgresql 9.2 is in stable and I was trying to figure out why my tomcat application was having stream errors. I didn't realize Gentoo's stable Postgres JDBC driver was still for version 8. This should be made stable.
In the meantime we had a bump to jdbc-postgresql-9.2_p1002 (23 Feb 2013) which also works very well here.
y u no stable? :) updating summary to p1002, as p1003 didn't bring any code change and p1004 has yet to enter tree (bug 496144)
Ah, yes; please stabilize =dev-java/jdbc-postgresql-9.2_p1003. Target keywords: amd64 ppc ppc64 x86 (@Andreas: 1003 is preferred so we can drop 1002 because of older EAPI)
amd64 stable
ppc64 stable
ppc stable
x86 stable. Closing.
