| | | | | | Ok. I made patches replacing all of "#if FALSE" or "#if 0" to "#ifdef NOT_USED" for current. I have tested these patches in that the postgres binaries are identical.

* Rearrange handling of MAXBACKENDS a little bit. The default settingTom Lane1999-02-2110-68/+79
| | | | | | | | | of MAXBACKENDS is now 1024, since all it's costing is about 32 bytes of memory per array slot. configure's --with-maxbackends switch now controls DEF_MAXBACKENDS which is simply the default value of the postmaster's -N switch. Thus, the out-of-the-box configuration will still limit you to 64 backends, but you can go up to 1024 backends simply by restarting the postmaster with a different -N switch --- no rebuild required.

* Allow maximum number of backends to be set at configure timeTom Lane1999-02-1914-392/+502
| | | | | | | | | (--with-maxbackends). Add a postmaster switch (-N backends) that allows the limit to be reduced at postmaster start time. (You can't increase it, sorry to say, because there are still some fixed-size arrays.) Grab the number of semaphores indicated by min(MAXBACKENDS, -N) at postmaster startup, so that this particular form of bogus configuration is exposed immediately rather than under heavy load.
