VACUUM FULL, power failure results in unrecoverable space

["Pierre Barre" <pierre@xxxxxxxx>]

Hello,

I encountered an issue while attempting to reclaim space from a heavily bloated table:

Initial analysis using https://github.com/ioguix/pgsql-bloat-estimation/blob/master/table/table_bloat.sql indicated approximately 600GB of bloat in the table.

I initiated a VACUUM FULL operation to reclaim this space, but during execution, the server experienced a power failure.

After server recovery:

1. The database came back online successfully

2. The space used by the in-progress table reconstruction was not freed

3. The newly wasted space (bloat + partial VACUUM FULL) is not shown using the above query, only the initial bloat.

Is there a way to reclaim this space without resorting to a full pg_dump and pg_restore cycle? 

Thanks.

Best,

Pierre
