Here is 2 approaches how to get to state where only PQsetSingleRowMode() is available. Both on top of REL9_2_STABLE branch.
a) Remove callback hooks, keep rowBuf, implement single-row-mode on top of that. This was posted before, I just additionally removed the PQgetRowData() function. git pull git://github.com/markokr/postgres.git single-row-mode1 https://github.com/markokr/postgres/commits/single-row-mode1 Commits: libpq: Single-row based processing libpq, dblink: Remove row processor API Advantage: makes easier to play with PQgetRowData() or potatial faster PGresult creation methods. Smaller change compared to libpq from 9.2beta than b). b) Revert row-callback changes completely, implement single-row-mode on top of virgin libpq. Only problem here was keeping fixes implemented as part of row-callback patch. Single-row-mode itself is quite simple. git pull git://github.com/markokr/postgres.git single-row-mode1 https://github.com/markokr/postgres/commits/single-row-mode1 Feature patch: https://github.com/markokr/postgres/commit/b5e822125c655f189875401c61317242705143b9 Commits: dblink: revert conversion to row processor API patch libpq: revert row processor API patch libpq: random fixes libpq: single-row mode dblink: use single-row-mode Advantage: smaller change compared to libpq from 9.1 than a). As the patch has suffered a lot from trying to provide both macro- and micro-optimization (on-the-fly row processing vs. more efficient row processing), maybe b) is safer choice for 9.2? In case somebody wants to look at the patches without git (or web), I attaches them as tgz too. -- marko
