Would it work to have it be multiline using here-doc syntax? It could be printed similarly to what psql does to error messages, with a prefix in front of each component (ERROR, STATEMENT, etc) and a leading tab for continuation lines. The last line is a terminator that matches something specified in the first error line. This becomes pretty complicated for a PID file, mind you. -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
