[GENERAL] How do you change the size of the WAL files?

[runner]

 

 Our WAL files are 16 Mb in size each.  I cannot find where you configure them 
to make them larger.  16 Mb is too small for our instalation.  If necessary, I 
can rebuild the entire cluster.  Our DBA initialized a new cluster and 
specified a larger WAL size but it stayed at 16 Mb.  Any info on this?

Thanks!
