ability to selectively exclude TOC items by ID.  Slightly more code but
much less likely to create future maintenance problems.

By default, table data objects are restored even if the
associated table could not be successfully created (e. g.
because it already exists). With this option, such table
data is silently ignored. This is useful for dumping and
restoring databases with tables which contain auxiliary data
for PostgreSQL extensions (e. g. PostGIS).
By default, table data is restored even if the creation command
for the table failed (e.g., because it already exists).
With this option, data for such a table is skipped.
This behavior is useful when the target database may already
contain the desired table contents. For example,
auxiliary tables for <productname>PostgreSQL</> extensions
such as <productname>PostGIS</> may already be loaded in
the target database; specifying this option prevents duplicate
or obsolete data from being loaded into them.

This option is effective only when restoring directly into a
database, not when producing SQL script output.
