Thread: Building PostgreSQL non-default Block size

Building PostgreSQL non-default Block size

From

The default block size which represents the page size is
8192 defined in pg_config.h.in.
 
I've been trying to increase that to 16384 and rebuild postgreSQL.
I was able to build it and it showed 16384 in the built pg_config.h.
 
After installation and use initdb, the pagesize is still the default 8192.
Any add'l config. procedure needed.

I think you did not do a full rebuild ("make clean" etc).
