Subject: BUG #17946: LC_MONETARY & DO LANGUAGE plperl - BUG
Date: Thu, 25 May 2023 15:21:26 +0000
Message-ID: <17946-3e84cb577e9551c3@postgresql.org> (raw)
The following bug has been logged on the website:
Bug reference: 17946
Logged by: Guido Brugnara
Email address: gdo@leader.it
PostgreSQL version: 12.15
Operating system: Ubuntu 20.04
Description:
After upgrading an application using Postgresql from version 10 to 12,
fields of type "money" are no longer generated with the € symbol but with
$.
I identified the problem that occurs when making use of functions with
"LANGUAGE plperl," see with the following queries to be executed in order:
# from shell ...
sudo su -c psql\ postgres postgres <<'__SQL__';
SET lc_monetary TO 'C';
SELECT 12.34::money AS price;
SET lc_monetary TO 'it_IT.UTF-8';
SELECT 12.34::money AS price;
SET lc_monetary TO 'en_GB.UTF-8';
SELECT 12.34::money AS price;
CREATE EXTENSION plperl;
SET lc_monetary TO 'C';
SELECT 12.34::money AS price;
DO LANGUAGE 'plperl' $$ my $rv = spi_exec_query(q{SELECT 12.34::money AS
price;}, 1);elog(NOTICE, $rv->{rows}[0]->{price});$$;
SET lc_monetary TO 'it_IT.UTF-8';
SELECT 12.34::money AS price;
DO LANGUAGE 'plperl' $$ my $rv = spi_exec_query(q{SELECT 12.34::money AS
price;}, 1);elog(NOTICE, $rv->{rows}[0]->{price});$$;
SET lc_monetary TO 'en_GB.UTF-8';
SELECT 12.34::money AS price;
DO LANGUAGE 'plperl' $$ my $rv = spi_exec_query(q{SELECT 12.34::money AS
price;}, 1);elog(NOTICE, $rv->{rows}[0]->{price});$$;
__SQL__
#end.
The first three SELECTs generate content with the currencies Dollar, Euro &
Pound, as expected, while the last three only with Dollar.
It would appear that after first DO LANGUAGE 'plper' call, LC_MONETARY even
if it is varied, has no effect in subsequent queries.
Any suggestions?
