Could you investigate a little and find out what actually happens?

Batch prepared correct, but something happened in BatchSend, i suppose, because i've got error when step-by-step debug "TSqlDBPostgresStatement.ExecutePrepared: Invalid array type ftBlob on bound parameter #3" (it is one of my blob fields) "in mormot.db.sql.postgres.pas line 656"

Please try with this last commit.

It works now, but only if there is no deleted rows. If i have any deleted row - table doesn't synchronise at all.
Maybe it affected not only tables with blobs, i don't know. In my case i do not delete rows in another tables.

I am not able to reproduce this behavior.

I create some orms on master
Then i created TOrm (1,2,3,4,5,6) with blob on master
Then delete record 4 with blob on master
then create some other orms on master

Then synchronise from master (sqlite) to slave (postgresql) (calling RecordVersionSynchroniseSlave from slave).
Nothing synchronised for TOrm (where i delete record), other orms synchronised well .

If i only create TOrm on master (do not delete) - synchronise works ok

In step-by-step debug i've got error
"Unexpected TSqlDBPostgresConnectionProperties.SharedTransaction (1,2)" in mormot.db.sql line 3701

Maybe it's because in prepared for sending batch i see in JSON that DELETE goes before all other lines? But this record cannot be deleted, it doesn't exist on slave server yet.

fails on TRestOrmServerBatchSend.AutomaticCommit after sequence POST-POST-POST-POST-DELETE-POST if ID for delete doesn't exists. Can't find out reason yet. No error message except "TSqlDBPostgresConnectionProperties.SharedTransaction( )"

upd: If i comment whole part for encDelete in TRestOrmServerBatchSend.ExecuteValue it fails too with the same exception

Sorry for the late reaction.

What does "if ID for delete does not exist" mean in your case?

I mean that record was deleted only on master db, it doesn't exist on slave db (sync was made after modifications on master db as i wrote before)
But when synchronization starts it tries to delete record which doesn't exist on slave db.
I suppose it's because of different transactions in post and delete chains
