Subject: Move vacuumlazy.c into access/heap/
X-Git-Url: http://git.postgresql.org/gitweb/-?a=commitdiff_plain;h=627348cb28788d9a54859e01abe90aafe9f44011;p=users%2Fandresfreund%2Fpostgres.git

Move vacuumlazy.c into access/heap/

It's heap table storage specific code that can't realistically be
generalized into table AM agnostic code.
