Use pg_get_triggerdef in pg_dump
Add a variant of pg_get_triggerdef with a second argument "pretty" that causes the output to be formatted in the way pg_dump used to do. Use this variant in pg_dump with server versions >= 8.5. This insulates pg_dump from most future trigger feature additions, such as the upcoming column triggers patch. Author: Itagaki Takahiro <itagaki.takahiro@oss.ntt.co.jp>
