use log_line_prefix='%m ..' and log_error_verbosity='verbose' in pg_regress

This makes debugging of errors and crashes a tad easier. Timestamps
with milliseconds allow more precise correlation of events from
multiple log files (coordinators vs. datanodes). Verbose error log
messages include file and line number where the error was reported.
