[pgpool-general: 697] Re: current transaction is aborted, commands ignored until end of transaction block

[Tatsuo Ishii]

Recently we have fixed problem with JDBC and unamed statement problem.
Can you try out the lastest snapshot(to be released as 3.1.4) of
pgpool-II 3.1 series? You can get it from:
http://git.postgresql.org/gitweb/?p=pgpool2.git;a=snapshot;h=7015e9f16d34c4f1d28096753638ca78d3d6a7f6;sf=tgz

Also debug log of pgpool (start pgpool with -d) would be helpfull.
