That code's been in there since PG 7.3, and no one before you has
complained.  Are you sure you've identified the problem correctly?

I am 99% sure that is the cause. If I put shmsys:ism_off=1 in /etc/ system
it ignores the SHM_SHARE_MMU flag and it works.
Maybe noone ever ran Postgres on Solaris on a VIA Epia system.
I haven't rebuilt postgres with my suggested patch (yet) so that's were the 1% doubt comes in.
I'll try to do that sometime this week.
