psql & query string length

Hi,

Well, I got psql to do it's thing, eventually. I've tested it for pretty
much everything, including \e, \g, \r, \i.
The one problem that I have had is that after about the third '\i long.sql',
I get a core dump, because sprintf moaned about string size complications.
The way I have structured it, memory is reallocated (re- malloc'd, not
realloc'd) every time the query is extended. I suspect that this is very
inefficient, and probably causing the system to hooch after loading long.sql
three times. The main thought that I have had is to extend the query buffer
in blocks of about 8k or 16k. I presume that once working with set memory
sizes, the memory usage will be substantially more efficient. Ideas?

Also, what's the deal with realloc? I tried it a couple of times, but it
really screwed me around (hence the re- malloc'ing). Or is it just a Bad
Move to use realloc?
