python modul pre-import to avoid importing each time

[Rémi Cura <remi.cura@xxxxxxxxx>]

Hey List,

I use plpython with postgis and 2 python modules (numpy and shapely).

Sadly importing such module in the plpython function is very slow (several hundreds of milliseconds).

I also don't know if this overhead is applied each time the function is called in the same session.

Is there a way to pre-import those modules once and for all,
such that the python function are accelerated?

Thanks,

Cheers,
