This is not error. It's just a message.

Postgresql uses some WAL files which are fixed in size and fixed in number for
a running instance. Obviously for a running instance there are going to be more
transactions than it can hold it in WAL. But transaction in WAL are
periodically flushed to main database. After this flush is complete, the WAL
file can be used to hold another set of transaction(rather WAL file name, if I
understand it correctly..) This message just says that it's reusing WAL files.
If this is too frequent, consider increasing wal_files in postgresql.conf, but
anything beyond 5 or 10 is overkill, given that each WAL file is 16MB in size..
