Why do you want to do that? Make it bigger, or smaller?

I would like to make it smaller. I use PostgreSQL in my Glom application
to host (initially) small amounts of data, starting a PostgreSQL
instance automatically whenever the data must be opened.

You can compile it smaller if you want, though you might hit some
problems nobody has seen before.
There appears to be a fair amount of "wasted" space, which tells me
nobody has ever really looked at this.
WAL files are 16MB, so you're main problem is there.
Use a compressed filesystem.

There might be some value in that if you expect your database instances
will always be small and low in write volume. Otherwise you're just
shooting yourself in the foot for a transitory gain.

You can recompile PostgreSQL with a smaller wal size, which will
reduce initial size a bit. I am not sure about the side effects though.
