RE: unable to write 'raise' messages to log file?

Hello Adrian,

Yes, if I call the function in PSQL then the expected message is displayed
the console display. Here is what is displayed in PSQL:

testdb=# select * from test.testwithbasictypearguments( 1,
2::numeric, '3' );
LOG: statement: select * from test.testwithbasictypearguments( 1,
2::numeric, '3' );
LOG: Test.TestWithArguments: i = 1, n = 2, t = 3
testwithbasictypearguments
----------------------------
0
(1 row)

testdb=#

Ian

Do they show up in a client? For example psql:

test_(aklaver)> create or replace function TestWithBasicTypeArguments( i
int, n numeric, t text) returns integer as $$

begin

raise log 'Test.TestWithArguments: i = %, n = %, t = %', i, n, t;

return 0;

end;

CREATE FUNCTION

test_(aklaver)> set client_min_messages = 'debug1';

test_(aklaver)> select testwithbasictypearguments(1, 2.5, 'test');
LOG: Test.TestWithArguments: i = 1, n = 2.5, t = test
testwithbasictypearguments
