If it is only 100k rows, then within a transaction: 1) delete all
rows, 2) insert all new rows, 3) commit, 4) vacuum.
don't try to compact the table with cluster or vacuum full since
you'll just re-expand it on the next synchronization.
There should be no blocking of your read access. This assumes your
copy is read-only, which you imply.
