RE: Consulta Migrar a 9.1 SOLUCIONADO

Hola Alvaro:

Esta es la función:

CREATE OR REPLACE FUNCTION audit.audit_table (
target_table pg_catalog.regclass,
audit_rows boolean,
audit_query_text boolean,
ignored_cols text []
)
RETURNS void AS
$body$
DECLARE
stm_targets text = 'INSERT OR UPDATE OR DELETE OR TRUNCATE';
_q_txt text;
_ignored_cols_snip text = '';
BEGIN
EXECUTE 'DROP TRIGGER IF EXISTS audit_trigger_row ON ' ||
quote_ident(target_table::text);
EXECUTE 'DROP TRIGGER IF EXISTS audit_trigger_stm ON ' ||
quote_ident(target_table::text);

IF audit_rows THEN
IF array_length(ignored_cols,1) > 0 THEN
_ignored_cols_snip = ', ' || quote_literal(ignored_cols);
END IF;
_q_txt = 'CREATE TRIGGER audit_trigger_row AFTER INSERT OR UPDATE OR
DELETE ON ' ||
quote_ident(target_table::text) ||
' FOR EACH ROW EXECUTE PROCEDURE audit.if_modified_func('
||
quote_literal(audit_query_text) || _ignored_cols_snip ||
');';
RAISE NOTICE '%',_q_txt;
EXECUTE _q_txt;
stm_targets = 'TRUNCATE';
ELSE
END IF;

_q_txt = 'CREATE TRIGGER audit_trigger_stm AFTER ' || stm_targets || '
ON ' ||
quote_ident(target_table::text) ||
' FOR EACH STATEMENT EXECUTE PROCEDURE
audit.if_modified_func('||
quote_literal(audit_query_text) || ');';
RAISE NOTICE '%',_q_txt;
EXECUTE _q_txt;

END;
$body$
LANGUAGE 'plpgsql'
