Narrow entries with natural whitespace might be okay as is. The
pg_aggregate example is better with blank lines, but another thing to
consider is that a comment that hugs a block is clear on which entries
it's referring to (pg_amop):

# btree integer_ops

# default operators int2
{ amopfamily => 'btree/integer_ops', amoplefttype => 'int2',
amoprighttype => 'int2', amopstrategy => '1', amopopr => '<(int2,int2)',
amopmethod => 'btree' },
{ amopfamily => 'btree/integer_ops', amoplefttype => 'int2',
amoprighttype => 'int2', amopstrategy => '2', amopopr => '<=(int2,int2)',
amopmethod => 'btree' },
{ amopfamily => 'btree/integer_ops', amoplefttype => 'int2',
amoprighttype => 'int2', amopstrategy => '3', amopopr => '=(int2,int2)',
amopmethod => 'btree' },
{ amopfamily => 'btree/integer_ops', amoplefttype => 'int2',
amoprighttype => 'int2', amopstrategy => '4', amopopr => '>=(int2,int2)',
amopmethod => 'btree' },
{ amopfamily => 'btree/integer_ops', amoplefttype => 'int2',
amoprighttype => 'int2', amopstrategy => '5', amopopr => '>(int2,int2)',
amopmethod => 'btree' },

# crosstype operators int24
{ amopfamily => 'btree/integer_ops', amoplefttype => 'int2',
...
[more blocks of integer ops
...]
amopmethod => 'btree' },

# btree oid_ops

With a blank line beween every entry, the comments would "float" more,
and the scope is not as clear. I'm okay with whatever the community
thinks, but at this point I'm inclined to leave things as they are and
focus on the other points of review for the next patchset.

While on the subject of viewing, I do have a badly outdated patch that
would create a postgres.sql file which would load into a development
schema so one could query the bootstrap data in a database without
running initdb. I could update it at a future point.
