I believe the PropertyShark team stores the layers in a mysql database,
if I remember their presentation (but I'd rather use postgres and
plpgsql functions as well, nice Cristiano).

I took the plpgsql way. Created a set of functions that generates the
mapfile blocks and store the tokens in several postgresql tables(using
traditional SQL relations).
Then I invoke the mapfile( id ) from database and pass the mapfile text
direct to mapscript.
With this, the mapfile creation has been managed by the database and did
not need any files.
Since all layers are already at database, I do not think those
generation steps take some much processing.
It is working for a few layers already loaded.
Current postgresql could also store them as XML. Recent mapserver could
parse xml mapfiles. But never implemented something this way.

Definitely leverage mapfile INCLUDEs
(http://mapserver.org/mapfile/__include.html
<http://mapserver.org/mapfile/include.html>). In your case, each
LAYER could be an include, and you could have a mapfile template
file that your shell script writes those include layers into.
I recently saw a presentation at FOSS4G-Europe from
PropertyShark, who manages thousands of layers, using includes,
and generates them through custom Perl scripts (you can read
about that discussion, or contact them, through the recent
Google+ discussion

Hi Everybody,
I need to create a script shell to build thousands of
mapfiles based on
postgis layers.
Which is the best way to accomplish this task?
Best regards,
Alex
