I created a trigger on a table that contains different log information.
This trigger launched a plsh function that execute a shell script to
print le new record a the table (with CUPS)
It worked fine but when I upgrated postgresql 7.4 -> 8.1 I was unable to
recompile properly pgplsh. So I copied old libraries and sql files from
a backup.
It works .
When I make a dump (pg_dump and psql ) the restoration fails because of
specific characters used in pgplsh. And I realized that there is poor
documentation on the web.
That is the reason why I consider now to change this system.
