Revision history for firebird_fdw

0.2.4   2014-02-06
        - libfq now supports a "client_encoding" connection parameter,
          which enables us to cover most reasonably common encoding
          combinations by passing the value provided by
          GetDatabaseEncodingName() to Firebird. See caveat in code
	  regarding compatibility between PostgreSQL and Firebird encoding
	  names.

0.2.3   2014-02-02
	- Default to PostgreSQL table name if no 'table_name' option
	  explicitly provided

0.2.2   2014-01-25
        - Implement basic transaction support

0.2.1   2014-01-23
	- Make extension compatible with PostgreSQL 9.2
	- Fix some regressions

0.2.0   2014-01-23
        - Implement basic connection caching
        - Fix implicit cast handling

0.1.6   2014-01-21
	- Push down bitwise operators << and >> (FB 2.1 and later)
	- Push down two-argument form of SUBSTRING()
	- Push down CONCAT()
	- Push down POSITION() / STRPOS()
	- Don't check for mutable functions - we are explicitly
	  whitelisting functions which can be pushed down
	  (need to double-check if that's a valid approach)

0.1.5   2014-01-20
	- Add basic Firebird version detection to ensure that only
	  functions available on the remote Firebird server are actually
	  pushed down
	- Push down functions COALESCE(), NULLIF()
	- Only push down SUBSTRING() if 2nd and 3rd arguments are INTs

0.1.4   2014-01-13
	- Prevent implicit casts from being pushed down to Firebird

0.1.3   2014-01-13
	- Partial pushdown of functions in WHERE clauses to Firebird
	- Ensure parameter "disable_pushdowns" is treated as a boolean
	- Add CREATE FOREIGN SERVER/CREATE FOREIGN TABLE parameter
	  "updatable", matching the postgres_fdw parameter

0.1.2   2014-01-11
	- Partial pushdown of WHERE clauses to Firebird
	- new CREATE FOREIGN SERVER parameter "disable_pushdowns"
	- CREATE FOREIGN TABLE parameter "table" renamed to "table_name"
	  (matching the postgres_fdw parameter and for consistency with the
	  column option "column_name")

0.1.1   2014-01-01
        - Add support for column aliases (column option "column_name")

0.1.0   2014-01-01
