Hi,

can any of the programming languages (perl, tcl) be used to exec a process on the server
and open files?
The scenario I have in mind would
- copy some fields of a table to an external text file
- have a script generate binary data from the text file
- load that data into a large object
The client would just
select rebuild()

​Do you want all of the processing to be done on the server side? You need to look into creating an _untrusted_ language such as PL/Tclu, plperlu, or PL/Python (which is always / only untrusted). Those languages allow full access to the TCL, PERL, or Python language, including running other processes (which would run under the postgres UNIX id, not the client's id).​


​Just to remind you: THIS CAN BE DANGEROUS TO THE HEALTH OF YOUR SERVER! Your gun. Your ammo. Your foot. Aim carefully.​
