I tried to test the patch. When sequences are more than the
batch-size, but not enough to make a complete batch of max size, I get
this error:
LOG: logical replication sequence synchronization for subscription
"sub1" - total unsynchronized: 118
LOG: logical replication sequence synchronization for subscription
"sub1" - batch #1 = 100 attempted, 100 succeeded, 0 skipped, 0
mismatched, 0 insufficient pemission, 0 missing,
WARNING: leaked hash_seq_search scan for hash table 0x5fcc78ff8f90
ERROR: no hash_seq_search scan for hash table "Logical replication
sequence sync worker sequences"
LOG: background worker "logical replication sequencesync worker" (PID
137165) exited with exit code 1
This is on creating 118 sequences. It can be easily reproduced by
reducing bath-size (MAX_SEQUENCES_SYNC_PER_BATCH) to say 5 and having
6 sequences in total. It seems we break out of the loop of creating a
batch only if batch_size >= MAX_SEQUENCES_SYNC_PER_BATCH. When we try
to access hash_seq_search() more than the entries present, it gives
the above error.
