[postgis-users] temporary geomtry table

[David Bitner]

Is it possible to have the output of a plpgsql function be a table?  I would
like to create a table that contained a regular grid of polygons.

What I eventually want is to be able to have a dataset that could be used in
mapserver that could be created by giving a function an extent and a grid
size (ie each cell is 100 acres in area).  This temporary dataset would then
be summarized with a line dataset. (ie crossings column in grid dataset had
number of times the cell had been crossed by a line from the line dataset).

Thanks
