* The reason that gprestore is in charge of creating the first pipe to ensure * that the first pipe is created before the first COPY FROM is issued.

Dollar-quoting logic is based on appendStringLiteralDQ() in pg_dump.

This function assumes that all identifiers are already appropriately quoted.

TODO: Uniquely identify COPY commands in the multiple data file case to allow terminating sessions.

Since we currently split schema and table on the dot (.), we can't allow users to filter backup or restore tables with dots in the schema or table.

The COORDINATOR and MASTER scopes are identical in function, we just support both so that creators of existing plugins as of GPDB 6 need not (re)write them to support the GPDB 7 verbiage.

Verbose progress bar logs every 10 percent.
