Subject: [PATCH v1] pg_recvlogical: Honor source cluster file permissions for
 output files

Commit c37b3d08ca6 attempted to preserve group permissions on pg_recvlogical
output files when group access was enabled on the source cluster. However,
the output files were still created with a fixed S_IRUSR | S_IWUSR mode,
preventing group-read permissions from being applied.

This commit fixes the issue by creating output files with pg_file_create_mode
instead of a hard-coded mode. This allows pg_recvlogical to correctly preserve
group permissions from the source cluster.

Backpatch to all supported branches.
