Get file size

[Lukas]

Hello,

maybe someone can give an idea how I cat get sizes of file which location
is know?
Lets say I have table with 200k records, in every record one column
indicates full file path on server for ex. "c:\temp\test.txt" etc. and I
want to fill that table with file sizes..
I was looking for function in plpgsql or plpgper languages, but I did not
found anything what could help me..

plpgsql is a trusted language so it can't access the file system.

I'd do it with plpgperlu but then again, Perl is my favorite language.

// Totally off-the-cuff (i.e. untested) example code to get you started
CREATE FUNCTION check_file_size (character varying)
RETURNS integer AS $BODY$
my ( $filepath ) = @_;
return 0 unless defined $filepath;
return -s $filepath; # returns size in bytes
$BODY$ LANGUAGE plperlu;
