In the 0001 patch, pg_get_sequence_data() exposes two new fields
log_cnt and page_lsn. I see that the later subscriber-side patch uses
both, the first one in SetSequence(). It is not clear from the
comments or the commit message of 0001 why it is necessary to use
log_cnt when setting the sequence. Can you explain what the problem
will be if we don't use log_cnt during sequence sync?
