Hi Simon,

I'm trying your patch, it was applied cleanly to master and compiled
ok. But since I started postgres I'm seeing a  99% of CPU usage:

guedes@betelgeuse:/srv/postgres/bgwriter_split$ ps -ef | grep postgres
guedes   14878     1  0 19:37 pts/0    00:00:00
/srv/postgres/bgwriter_split/bin/postgres -D data
guedes   14880 14878  0 19:37 ?        00:00:00 postgres: writer
process
guedes   14881 14878 99 19:37 ?        00:03:07 postgres: checkpointer
process
guedes   14882 14878  0 19:37 ?        00:00:00 postgres: wal writer
process
guedes   14883 14878  0 19:37 ?        00:00:00 postgres: autovacuum
launcher process
guedes   14884 14878  0 19:37 ?        00:00:00 postgres: stats
collector process

Best regards.
