hstore_compact.rb hstore_name

This removes all free space (unused file space) from the HStore. Stores the original HStore files in ./hstore_backup by default.

  Examples:
     ruby hstore_compact.rb hstore_name description version
     cd ../tst
     ruby -r locana.rb ../hstore/hstore_compact.rb locana.ls "Locana Objects" "1.00"
     cd ../applets
     ruby -r notes.rb ../hstore/hstore_compact.rb notes.hs "Locana Notes" "1.00"
     ruby -r reminders.rb ../hstore/hstore_compact.rb reminders.hs "Locana Reminders" "1.00"
     ruby -r todos.rb ../hstore/hstore_compact.rb todos.hs "Locana Todos" "1.00"
     ruby -r timer.rb ../hstore/hstore_compact.rb timer.hs "Locana Timer Data" "1.00"
     # the -r is needed so backup_store knows what to do with the internal data stored in each HStore.

  To see the contents of the HStores:
     cd ../tst
     ruby -r locana.rb ../hstore/hstore_dump.rb locana.ls
     cd ../applets
     ruby -r notes.rb ../hstore/hstore_dump.rb notes.hs
     ruby -r reminders.rb ../hstore/hstore_dump.rb reminders.hs
     ruby -r todos.rb ../hstore/hstore_dump.rb todos.hs
     ruby -r timer.rb ../hstore/hstore_dump.rb timer.hs

This eliminates all free space from the HStore and/or allows you to change the description and version stored in the descriptor. Call this method (or tst_hstore_compact.rb) when the HStore gets too bloated with free space. If this fails, the original files should remain in the current, unchanged state.

This exports the HStore, creates a new HStore, imports from the exported file, and if everything works correctly renames the new HStore to the old name. Descriptor is a Hash. If you provide a descriptor, it will replace the old descriptor.

Returns export_filename, export_record_count, import_record_count, error_count
