There are many posts about "...FATAL: Could not create shared memory segment.
Function not implemented..." when trying initdb using cygwin, but...I get
the same error with straight Linux (pgsql 7.4.1; 2.6.4-ck2 kernel). It
installed fine with RH9 with either a RH2.4.20-8 or a vanilla 2.6.4 kernel, but I
recently switched to Gentoo 2004.0 with the aforementioned kernel. Is this a
problem with the ck patches? Might this be fixed with pgsql 7.4.2? Is there some
other problem? (FWIW, I also posted this on one of the Gentoo forums and
some people have looked at it but I haven't gotten any suggestions.) Thanks!
