tds_fdw-1.0.5

tds_fdw-1.0.5

Today, I am releasing version 1.0.5 of tds_fdw, a TDS foreign data wrapper. It can be used to connect to Microsoft SQL Server and Sybase databases. This should work on PostgreSQL 9.1+.

New in this version:

• Fixed an issue that caused problems for versions older than PostgreSQL 9.4. See issue #34.

tds_fdw-1.0.4

tds_fdw-1.0.4

Today, I am releasing version 1.0.4 of tds_fdw, a TDS foreign data wrapper. It can be used to connect to Microsoft SQL Server and Sybase databases. This should work on PostgreSQL 9.1+.

New in this version:

• Added support for PostgreSQL 9.5. See issue #33. Thanks to GitHub user @mc-soi for this patch!
• Fixed several memory leaks. See issue #29.
• Implemented a special conversion for the DATETIME type, so that it can be converted into PostgreSQL's timestamp type without tinkering with the system's locale settings. See issues #28, #21, and #13.
• Added some variables that provide a way to write tds_fdw memory usage to the PostgreSQL error log for diagnostic purposes. These variables are called tds_fdw.show_before_row_memory_stats, tds_fdw.show_after_row_memory_stats, tds_fdw.show_finished_memory_stats.

This version does not support write operations, where push-downs, column push-downs, or join push-downs.

tds_fdw-1.0.3

tds_fdw-1.0.3

Today, I am releasing version 1.0.3 of tds_fdw, a TDS foreign data wrapper. It can be used to connect to Microsoft SQL Server and Sybase databases. This should work on PostgreSQL 9.1+.

New in this version:

• Fixed bug that made tds_fdw treat empty strings as NULL in some versions of the TDS protocol. See issue #18.
• Added "msg_handler" foreign server option. If set to "notice", DB-Library messages are turned into PostgreSQL notices. If set to "blackhole", DB-Library messages are ignored. By default, "msg_handler" is set to "blackhole." See issue #22.
• Removed "database" foreign table option. Use "database" foreign server option instead.
• The "row_estimate_method" foreign table option can now be set server-wide for a foreign server.
• General code refactoring.

This version does not support write operations, where push-downs, column push-downs, or join push-downs.

tds_fdw-1.0.2

tds_fdw-1.0.2

Today, I am releasing version 1.0.2 of tds_fdw, a TDS foreign data wrapper. It can be used to connect to Microsoft SQL Server and Sybase databases. This should work on PostgreSQL 9.1+.

New in this version:

• Fixed bug causing negative row count estimations in query plans. See issues #14 and #15.
• Added database and dbuse options to foreign server objects. This also fixes issues with Microsoft Azure. See issues #23.
• Added tds_version option to foreign server objects. See issue #24.
• Added row_estimate_method option to foreign table objects. Default value is execute. If set to execute, tds_fdw will execute a query on the remote table and count the number of rows used to build the query plan. If set to showplan_all, tds_fdw will use MS SQL Server's SET SHOWPLAN_ALL feature to get the estimated the number of rows used to build the query plan. I hope to add a Sybase optimization eventually.
• General code refactoring, mostly related to options and row estimations.

This version does not support write operations, predicate push-downs, or join push-downs.
