Re: [GENERAL] Memory leak

Hi all I have just isolated a big problem in one of my applications and it turns out to be a memory leak in postgresql on a VERY basic piece of functionality It just caused a backend to grow to 133 MB in 4 hours running, which is obviously not good Simple piece of C code to demonstrate this: for (loopa=0;loopa < 100000;loopa++) { result=PQexec(dbase,"create table test_table ( " "value int,wordnum int,refnum int,word text)"); PQclear(result); result=PQexec(dbase,"drop table test_table"); PQclear(result); } And watch the memory risssssssse On an aside, any idea how long till there is a fix for the vacuum analyze crash, as it is cripling me having that happen. Final question... Is there a really really good reason that when a backend crashes, all the other backends die and close connection rather than simply re-initialising their connections. If it just reinitialised transparently that would make it a LOT easier than having to have an extra test to see if the backend has mysteriously crashed after EVERY query! Thanx M Simms -- #define z(x,y) for (x=0;x<y;x++){ main(){long int i[3]={1214606444,1864390511,1919706122};int x,y; z(x,3)z(y,4)putchar((i[x]>>((3-y)<<3))&(255)); }}}
