cannot suppress full warining

[gbisschoff]

suppressWarnings(exp) only suppresses half of the messgage. The part of the warning that is related to the psql error (probably received from the database) cannot be suppressed. E.g

add_user(test_con,"NamE","Email","Password") returns the psql error and an R warning

Error in postgresqlExecStatement(conn, statement, ...) : RS-DBI driver: (could not Retrieve the result : ERROR: relation "users" does not exist LINE 1: INSERT INTO users (name,email,password) values('NamE','Email... ^ )

Warning message: In postgresqlQuickSQL(conn, statement, ...) : Could not create execute: INSERT INTO users (name,email,password) values('NamE','Email','6eb12216e1e7515eda6da7104bccf246') RETURNING user_id;

When suppressing warnings suppressWarnings(add_user(test_con,"NamE","Email","Password")) it still returns the first part:

Error in postgresqlExecStatement(conn, statement, ...) : RS-DBI driver: (could not Retrieve the result : ERROR: relation "users" does not exist LINE 1: INSERT INTO users (name,email,password) values('NamE','Email... ^ )

Add the message returned from postgres to the R warning message rather than in a separate print. (PS it makes my unit test look dirty)
