Thread: pgsql: Add SHELL_ERROR and SHELL_EXIT_CODE magic variables to psql.
Add SHELL_ERROR and SHELL_EXIT_CODE magic variables to psql. These are set after a \! command or a backtick substitution. SHELL_ERROR is just "true" for error (nonzero exit status) or "false" for success, while SHELL_EXIT_CODE records the actual exit status following standard shell/system(3) conventions.
