>Development in built-in connection pooling will be continued in https://github.com/postgrespro/postgresql.builtin_pool.git
The branch (as of 0020c44195992c6dce26baec354a5e54ff30b33f) passes pgjdbc tests: https://travis-ci.org/vlsi/pgjdbc/builds/368997672 Current tests are mostly single-threaded, so the tests are unlikely to trigger lots of "concurrent connection" uses. The next step might be to create multiple schemas, and execute multiple tests in parallel. Vladimir
