Hi,

We are planning to add a C extension (
https://github.com/petropavel13/pg_rrule) to our shared postgresql cluster,
and wondering what are the risk? (looking for the worst case scenario here)

If there is a SIGSEGV, SIGBUS, SIGABRT ..., is the whole server stopping,
or just the request?

Knowing that the extension is only used in select statement, is there a
risk of (on disk) data corruption?

Is the risk limited to the current database? (the extension will only be
used by 1 application with 1 database, and we prefer not to impact other
applications/databases)

Are there any techniques to limit/mitigate these risks?
(configuration/compile flags/...)

Thanks in advance
Etienne
