+pgbouncer (Lightweight connection pooler for PostgreSQL)
+
+pgbouncer is a PostgreSQL connection pooler. Any target application
+can be connected to pgbouncer as if it were a PostgreSQL server,
+and pgbouncer will create a connection to the actual server, or it
+will reuse one of its existing connections.
+
+The aim of pgbouncer is to lower the performance impact of opening
+new connections to PostgreSQL.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
