Best I can do is a proof of concept in plpythonu for determining locale
decimal point:
test=# SHOW lc_numeric ;
lc_numeric
-------------
en_US.UTF-8
(1 row)
test=# DO $$
import locale
rs = plpy.execute("SHOW lc_numeric")
lc_n = rs[0]["lc_numeric"]
locale.setlocale(locale.LC_NUMERIC, lc_n)
d = locale.nl_langinfo(locale.RADIXCHAR)
plpy.notice("Decimal point is " + d)
$$ LANGUAGE plpythonu;
NOTICE: Decimal point is .
CONTEXT: PL/Python anonymous code block
DO
test=# set lc_numeric = 'nl_NL.utf8';
SET
test=# DO $$
import locale
rs = plpy.execute("SHOW lc_numeric")
lc_n = rs[0]["lc_numeric"]
locale.setlocale(locale.LC_NUMERIC, lc_n)
d = locale.nl_langinfo(locale.RADIXCHAR)
plpy.notice("Decimal point is " + d)
$$ LANGUAGE plpythonu;
NOTICE: Decimal point is ,
