You just broke it.
Those buffers are not used to hold struct passwd's, but to hold
multiple character strings to which the struct passwd will point;
any one of which could be long, but particularly the home directory
path.
My man page for getpwuid_r says that the minimum recommended buffer size
is 1024.

I think we should revert it entirely. A small buffer size risks
breaking things unnecessarily, and as I replied earlier, the request
to make libpq run in a less-than-8K stack is not reasonable anyway.
