An important part of performing a migration from Oracle to PostgreSQL is selecting the right tool for helping with the conversion between systems.
Creation and clean up of WAL files in the primary's pg_wal folder (pg_xlog prior to PG10) is a normal part of PostgreSQL operation. The WAL files on the primary are used to ensure data consistency during crash recovery. Use of write-ahead logs (also called redo logs or transaction logs in other products) is common for data stores that must provide durability and consistency of data when writing to storage. The same technique is used in modern journaling and log-structured filesystems.
A well tuned production Postgres database is capable of easily running thousands or up to hundreds of thousands of queries per second on a beefy instance.
