harbour-core/harbour/contrib/hbpgsql/postgres.c
Viktor Szakats 46298a0dd6 2010-11-21 20:42 UTC+0100 Viktor Szakats (harbour.01 syenar.hu) 
* contrib/hbpgsql/postgres.c
    + Added PQPREPARE(), PQEXECPREPARED(). Based on code donated by
      Lorenzo Fiorini. Modified to compile with current Harbour,
      changed parameter handling and error checking, and changed
      to return GC collected result pointer. (I didn't make any
      tests, so pls do)

  * contrib/hbpgsql/hbpgsql.hbp
  - contrib/hbpgsql/pgrdd.prg
  - contrib/hbpgsql/tests/tstpgrdd.prg
    - Deleted experimental USRRDD for PGSQL.
