Should capitalize at least the non-text one ? And maybe the text one for
consistency ?
+ ExplainPropertyInteger("WAL fpw", NULL,
And add the acronym to the docs:
$ git grep 'full page' '*/explain.sgml'
doc/src/sgml/ref/explain.sgml: number of records, number of full page writes and amount of WAL bytes
"..full page writes (FPW).."
Should we also change vacuumlazy.c for consistency ?
+ _("WAL usage: %ld records, %ld full page writes, "
+ UINT64_FORMAT " bytes"),
