Bruce Momjian	c6411605e1	I have created a small patch that makes possible to compile pgsql on newer ... Cygwin snapshots (tested on 990115 which is recommended to use - it fixes some errors in B20.1) And I have another patch for including <sys/ipc.h> before <sys/sem.h> in backend/storage/lmgr/proc.c - it is required due the design of cygipc headers Dan	26 years ago
Vadim B. Mikheev	4793740367	XLOG (also known as WAL -:)) Bootstrap/Startup/Shutdown. ... First step in cleaning up backend initialization code. Fix for FATAL: now FATAL is ERROR + exit.	26 years ago
Tom Lane	e812458b27	Several changes here, not very related but touching some of the same files. ... * Buffer refcount cleanup (per my "progress report" to pghackers, 9/22). * Add links to backend PROC structs to sinval's array of per-backend info, and use these links for routines that need to check the state of all backends (rather than the slow, complicated search of the ShmemIndex hashtable that was used before). Add databaseOID to PROC structs. * Use this to implement an interlock that prevents DESTROY DATABASE of a database containing running backends. (It's a little tricky to prevent a concurrently-starting backend from getting in there, since the new backend is not able to lock anything at the time it tries to look up its database in pg_database. My solution is to recheck that the DB is OK at the end of InitPostgres. It may not be a 100% solution, but it's a lot better than no interlock at all...) * In ALTER TABLE RENAME, flush buffers for the relation before doing the rename of the physical files, to ensure we don't get failures later from mdblindwrt(). * Update TRUNCATE patch so that it actually compiles against current sources :-(. You should do "make clean all" after pulling these changes.	26 years ago

Remember blkno of new root page in BTPageOpaque of left/right siblings when root page is splitted.	27 years ago
Tom Lane	9d197856dd	Rearrange handling of MAXBACKENDS a little bit. The default setting ... 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.	27 years ago
Tom Lane	4c31393135	Reorder startup ops so that if preallocation of semas fails, ... postmaster will release whatever it did get before dying.	27 years ago
Tom Lane	e77b630cf0	Allow maximum number of backends to be set at configure time ... (--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.	27 years ago
