my own mail servers do this.  each virtual has it's own file and can be edited
individually.  for performance reasons (e.g. the more maps you have, the more
lookups postfix has to do to find an entry...which tends to defeat the purpose
of hashed db map files), i concatenate them into one file for use by postfix.

also trivial.  you can have as many virtual alias maps (or any other maps) as
you want.

for optimum performance (and minimal use of file handles), though, you're much
better off concatenating multiple files of the same type into just one file for
postfix to use.  this is easy to do with make and cat.

as you say, postfix doesn't allow direct use of pipes in virtual tables for
security reasons.  virtuals can point to local aliases which can be pipes.

personally, i'd choose security over a trivial inconvenience...especially when
that inconvenience can be worked around with very simple scripting.

the workaround is also documented.
