bin/repl: text mode: also match w/ suffix (eg. _verbatim)

bugfix: /README.TXT: Maintenance: VegCore data dictionary: apply new data dict mappings: need to use postprocess rather than import runscript target, so that the command also works on an svn checkout without the flat files (the flat files are not needed for the staging table renaming)

lib/sh/db.sh: psql(): $verbose_ok: renamed to $bypass_ok for clarity, because this applies only to the `--output /dev/fd/41` bypass (which when not possible, requires turning off verbose output

fix: lib/sh/db.sh: psql(): added $output_data switch analogous to what mysql() has. this causes query results of eg. void-returning functions to be correctly filtered by the logging mechanism, rather than output to stdout.

lib/sh/db.sh: psql(): replaced `test "$verbose_ok" && can_log` with bool var $verbose_

fix: lib/sh/db.sh: psql(): $verbose_: renamed to $verbose_ok for clarity

fix: lib/sh/util.sh: stdout_contains(): add another pipe_delay because the `grep` statement was sometimes getting printed before its filtered output

schemas/util.sql: set_col_types(): use simpler util.eval() instead of manual EXECUTE/util.debug_print_sql()
