+Q: Why can't I reload the SQL script I dumped in the SQL window?
+
+A: The following limitations currently exist in SQL script execution:
+
+       * Only uploaded SQL scripts can contain COPY commands and for
+         this to work, you must have PHP 4.2 or higher.
+
+       * 'psql' commands such as '\connect' will not work at all.
+
+       * Multiline SQL statements will not work, eg:
+
+               CREATE TABLE example (
+                       a INTEGER
+               );
+
+       * You cannot change the current database or current user during
+         the execution of the script.
+
+   We do intend to work on some of these limitations in the future, but
+   some of them are PostgreSQL restrictions and we recommend using the
+   'psql' utility to restore your full SQL dumps.
+
+Q: Why is there never any information on the 'Info' page of a table?
+
+A: The Info page will show you what other tables have foreign keys to the
+   current table and some data from the PostgreSQL statistics collector.
+   The stats collector is not enabled by default in PostgreSQL.  To enable
+   it, look in your postgresql.conf file for the stats_* options.  Just
+   make them all 'true' and restart PostgreSQL.
