Tomas Vondra 167075be3a Add strict_multi_assignment and too_many_rows plpgsql checks ... Until now shadowed_variables was the only plpgsql check supported by plpgsql.extra_warnings and plpgsql.extra_errors. This patch introduces two new checks - strict_multi_assignment and too_many_rows. Unlike shadowed_variables, these new checks are enforced at run-time. strict_multi_assignment checks that commands allowing multi-assignment (for example SELECT INTO) have the same number of sources and targets. too_many_rows checks that queries with an INTO clause return one row exactly. These checks are aimed at cases that are technically valid and allowed, but are often a sign of a bug. Therefore those checks are expected to be enabled primarily in development and testing environments.
