Re: [GENERAL] [HACKERS] psql
Well here's the thing. Before i was trying to use ShmemInitStruct in buf_init.c. The problem with this is that you can't shrink or grow shared memory. That is why i switched over and just used malloc. So i seem to be in a big dilemma, on one hand, if i use malloc, i can't keep this info i need; and on the other if i use shmeminitstruct then i can't shrink or grow the BP clusters. But i will try to test your hypothesis to see if shared memory will take care of this.

The current version in the web is based off of 7.2 code, but I hope to refresh with a beta based on 7.3 code in the next few weeks. http://telegraph.cs.berkeley.edu/telegraphcq -- Pip-pip Sailesh http://www.cs.berkeley.edu/~sailesh ---(end of broadcast)--- TIP 7: don't forget to increase your free space map settings
