The Enterprise channel covers all topics related to Linux and open-source within enterprise environments.
Hadoop is an Apache project to provide for reliable, scalable, distributed computing that's open-source.
PhpMyAdmin is a tool written in PHP for MySQL server database administration.
PostgeSQL is a leading open-source SQL database server.
Samba is an open-source SMB/CIFS protocol implementation for supporting interoperable file and print services from Windows on Linux/Unix systems.
Web servers and other server software projects are covered by this sub-channel.

This Month's Activity
- ssl: Drop support for older OpenSSL versions
SPICE - Christophe Fergeau: SSL_OP_NO_COMPRESSION was introduced in OpenSSL_0_9_8k, which is no longer supported.
- Report failure to start a background worker
PostgreSQL - Robert Haas: When a worker is flagged as BGW_NEVER_RESTART and we fail to start it, or if it is not marked BGW_NEVER_RESTART but is terminated before startup succeeds, what BgwHandleStatus should be reported? The previous code really hadn't considered this possibility (as indicated by the comments which ignore it completely) and would typically return BGWH_NOT_YET_STARTED, but that's not a good answer, because then there's no way for code using GetBackgroundWorkerPid() to tell the difference between a worker that has not started but will start later and a worker that has not started and will never be started.
- Support Parallel Append plan nodes
PostgreSQL - Robert Haas: When we create an Append node, we can spread out the workers over the subplans instead of piling on to each subplan one at a time, which should typically be a bit more efficient, both because the startup cost of any plan executed entirely by one worker is paid only once and also because of reduced contention.
- Fix EXPLAIN ANALYZE of hash join when the leader doesn't participate
PostgreSQL - Andres Freund: If a hash join appears in a parallel query, there may be no hash table available for explain.c to inspect even though a hash table may have been built in other processes.
- Update version for v2.11.0-rc4 release
QEMU - Peter Maydell
- When VACUUM or ANALYZE skips a concurrently dropped table, log it
PostgreSQL - Robert Haas: Hopefully, the additional logging will help avoid confusion that could otherwise result.
- Support boolean columns in functional-dependency statistics
PostgreSQL - Tom Lane: There's no good reason that the multicolumn stats stuff shouldn't work on booleans.
