Look at

It's clean and simple, and I particularilly like the SQL syntax coloring

Will look into it, but, the bunch of DHTML it seems to be making use of
means I might not try too hard...<smile>
Thanks though.

there is no official 64bit binaries, but there are a few other sources,
where you can get pre-compiled 64bit binaries (
http://www.apachelounge.com/download/win64/ for example) or you can compile
it yourself.

32bit applications usually can't allocated more than 2GB memory (with 4GT
you can raise that per process memory limit to 3GB and with PAE, you can
raise the system wide 4GB limit, see
http://msdn.microsoft.com/en-us/library/windows/desktop/aa366796(v=vs.85).aspx
)
if you need more than that, you have to use a 64bit version of PHP.
that isn't officially supported, but you can either try to compile
yourself, or you can try downloading from unofficial sources ( like
http://www.anindya.com/ ) or there are a few wamp packages offering
complete 64 bit stack.
for the record: if you plan to use apache + mod_php5, both apache and php
has to be 64bit binaries, but if you use cgi/fastcgi then only your php
binary has to be 64bit, as it will be a separate process in this case.

you can use more than 2GB memory, however you can still run into some
issues, for example
The root problem is that Windows "WIN64" is a 64P architecture. Linux and

so you can't have longs/ints larger than 2147483647, which means for
example than you can have problems handling files over the size of 2GB:

migrating from postgres to mysql wouldn't change the situation, you need a
64-bit php binary to be able to use more than 2(3 with the 4GT option) GB
memory
