Hi, I'm having the issue with PG 15.13. We tried adding more memory (logical_decoding_work_mem) to 5 GB, but it still doesn't work, and the process "replicate" stops with the following error:
"CDC Fetch Failed: An unexpected connection error occurred while attempting to replicate data from the source. Make sure your connection profile settings are correct. If the problem persists, contact Google Support."
"ERROR: Invalid memory allocation request, size 1674007328."
We have another environment with PG 15.12, and it works perfectly.
This case has have relation with https://www.postgresql.org/message-id/CALDaNm2sGfKsZwm8rG132N_i0AvyxkYu8TL46kNcx7KwAUABxA%40mail.gmail.com

Yes, I also feel that you faced the same issue. Since the issue happens lower layer than the logical decoding, logical_decoding_work_mem can't work to avoid the ERROR. We are discussing how we fix.
