Log Message:
-----------
further improvements of the database API:
- unify postgres, unixodbc and mysql code, error and debug messages
- move the column allocating logic into the DB core API
- change the all three modules to use this function
- change postgres module to use the memory memory management methods of the core
- add a flag to the db_val_t type that indicates if the (string) memory must be
freed
- don't try to free the static NULL values in db_free_row
- change core row freeing method to evaluate the memory status flag
- change the postgres module to set this flag
- add some memsets to the mysql and unixodbc module for more safety and also
ensure the correct working of the free flag
- fix database TYPE flags in mysql module, they will be removed for 5.2 and are
also obselete since 3.X times
- change column names allocation logic in postgres to match the unixodbc and
mysql
behaviour, don't copy the names
- some smaller documentation improvements and cleanups
- tested only with testsuite so far
works that still needs to be done:
- modify the db_berkeley, dbtext and flatstore module to use the core API
- modify the postgres, db_berkeley driver that they don't copy the values
returned from the driver
