github laurenz/oracle_fdw ORACLE_FDW_2_0_0
Release 2.0.0

7 years ago

Incompatible changes:

  • Remove the deprecated option plan_costs, since it is not very useful and is a maintenance burden.
    After an upgrade, tables with this option set should be updated with:

    ALTER FOREIGN TABLE ... OPTIONS (DROP plan_costs);
    

Enhancements:

  • Push down 2-way inner joins in SELECT statements if all conditions can be pushed down.
    Patch by Tatsuro Yamada (@yamatattsu), courtesy of NTT OSS Center.

Bugfixes:

  • oracle_fdw crashed on Windows if queries use a NULL parameter or an empty subselect.
    Report by PAscal Lemoy (@legrandlegrand).

  • Reading srid.map sometimes caused errors even if everything was alright.
    Report by Paul Dziemiela (@pauldzy), analysis by Christian Ullrich (@chrullrich).

  • Don't push down expressions with CLOB column references.
    Because of Oracle's inability to use CLOB in SQL expressions, this could lead to errors like

     ORA-00932: inconsistent datatypes: expected - got CLOB
    
  • Fix bug in pg_terminate_backend handling.
    pg_terminate_backend (or SIGTERM) was not handled correctly, since neither was the Oracle query canceled nor did the backend terminate.
    Reported by Dmitry Chirkin (@josser).
