Segmentation Fault (Logical Replication)

"M Rehman Kahloon" <m.rehman@3gca.org> writes:

I am facing very critical issue with my master database when
implemented logical replication using pglogical and built in replication
feature ( publisher using postgrSQL 10 and subscription using PostgreSQL
11).
DB crashing frequently with error 'Segmentation Fault' error. Same issue
when seeting pg-wal logical and replica.

There's nowhere near enough information in this report for anyone to
help you. Please see

https://wiki.postgresql.org/wiki/Guide_to_reporting_problems

and

https://www.postgresql.org/docs/11/bug-reporting.html

for some advice about what to put in a useful trouble report.
Since you're getting crashes, we'd probably also wish to see
a stack trace,

Impossible to say if that's Postgres problem without at least a
backtrace (even better a reproducible scenario), but you could also
consider contacting the maintainers of pglogical:
