Обсуждение: Troubles with PL/Perl in PgSQL
Hallo!
I'm new in PgSQL and I try to migrate from InterBase (Firebird) to PgSQL.
I have a trouble with call ANY plperl function.
I have the very simple function:
---------------------
CREATE FUNCTION myint(integer) RETURNS integer AS $$
my $result = $_[0];
return $result;
$$ LANGUAGE plperl;
---------------------
And when I try to call this function, I got the error:
---------------------
$ psql test
Welcome to psql 8.0.3, the PostgreSQL interactive terminal.
Type: \copyright for distribution terms
\h for help with SQL commands
\? for help with psql commands
\g or terminate with semicolon to execute query
\q to quit
test=# select * from myint(5);
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
!>
---------------------
From the /var/log/messages
Jul 27 18:17:24 ibserver postgres[57180]: [5-1] FATAL: the database
system is in recovery mode
I use FreeBSD 5.4 with PostgreSQL 8.0.3.
PgSQL was builded from sources with --with-perl option. Other options
have defaults values.
Thanks for any replies!

And here that I have noticed: on a home computer this truoble is not present. However on the server and my home PC - the kernel and the system environment are almost absolutely identical - FreeBSD 5.4 (cvsup on Tue Jul 26 21:24:24 MSD 2005). (except SMP support in the kernel and two options sysctl - for hypertrading on the server). SysV IPC options are identical too. Possibly, I've gape any bug report about a problem using SMP kernel? > > >>server closed the connection unexpectedly >> This probably means the server terminated abnormally >> before or while processing the request. >>The connection to the server was lost.

The syntax that you have used will (should) cause the return value to be output once for every record in the table. > (table test exists but has no records), I got the > same error. > > And here that I have noticed: on a home computer > this truoble is not > present. > However on the server and my home PC - the kernel > and the system > environment are > almost absolutely identical - FreeBSD 5.4 (cvsup on > Tue Jul 26 21:24:24 > MSD 2005). > (except SMP support in the kernel and two options > sysctl - for > hypertrading on the server). > SysV IPC options are identical too. > > Possibly, I've gape any bug report about a problem > using SMP kernel? AFAIK there should be no problem with using SMP.

Attempting reset: Failed. Did you get a core dump? In released versions of PostgreSQL core dumps are usually under $PGDATA/base/<database oid>, although some systems can be configured to put them elsewhere (e.g., by using FreeBSD's kern.corefile sysctl setting). If you got a core dump then it might be useful to see a stack trace. If you didn't get a core dump then you might need to change the coredumpsize resource setting so you do get one. -- Michael Fuhr http://www.fuhr.org/~mfuhr/
