[postgis-users] pgsql2shp segfault by multipolygon export

[strk at refractions.net]

I've made a test on a 64bit machine with 1.0 branch.
Dump of 32768 multipolygons worked fine.
I suspect the bug to be in the hexwkb output if the 0.9
backend possibly corrupted.

You might try undefining USE_WKB in your 0.9 version of
pgsql2shp.c to see if the error goes away.
