Hi.
1. Why should one prefer built-in logical replication in pg-10 to pglogical,
does it do anything pglogical doesn't?
It seems pglogical is more feature-rich...
2. As I understand built-in logical replication in pg-10 doesn't support large-objects, which we use a lot. Does pglogical replicate large objects? I cannot find any notes about large-objects under
"Limitations and Restrictions": https://www.2ndquadrant.com/en/resources/pglogical/pglogical-docs/
You may do a simple test, create a table with a largeobject and try to read the logical stream, if it cannot represent the lo_import, lo_open, lowrite, lo_close (and I 'd bet they can't be encoded)
then neither pglogical (being based on the same logical decoding technology) will support them.
