I'm not sure, but I think, that it can be problem of x86 architecture, 
not of libpq, becouse I have problems like this with data tables in 
memory, what are "static" in procedures (defined and used in procedures 
only). I'm programming in Pascal (I'm old school programmer knowing 
C/C++, but I have too much old good routines for Pascal). Free Pascal is 
fully compatible with C, so it brings this same problems with all 
things, as in C. When I get memory dynamically, I don't get problem like 
this, but You know - maybe I'm wrong...
