<div class="WordSection1"><p class="MsoNormal">Hi.  Has anyone had experience building PostgreSQL to support Address
SpaceLayout Randomization (ASLR)?  I recently took a brute-force approach (compiling everything with -fPIC and
specifying-pie on all executables).  This worked, but a (very superficial) performance test indicated a high cost
(around50%, much more than I expected).  This was on 64-bit Linux x86.<p class="MsoNormal"> <p class="MsoNormal">Google
turnsup some references to the Ubuntu distribution of version 8.3 being built this way but nothing much more
interesting.<pclass="MsoNormal"> <p class="MsoNormal">I’d appreciate any information or help anyone can give me on
this. Thanks.<p class="MsoNormal"> <p class="MsoNormal"> <p class="MsoNormal"> </div>
