This is an experiment to use JSONB instead of text in
ps_oplog, converting lines as they are downloaded. The binary data is then forwarded tops_data_andps_untypedtables unchanged (relying on the fact that they're non-strict, so we can push binary data into theTEXTcolumn).I have not done any benchmarks on this, but the idea is that this could potentially speed up queries. We also need to check the impact of the conversion on sync performance though.
