Log Message:

Leonardo Cezar patches:

One of them to fix a odd behavior when we had views in schema to
schema to extract some reporter.
Previously we got an error on trying to get statistcs from a view,
since views hasn't stats.

The other one to choose which table(s) we want to collect information
with --table=foo,bar,x ... option.

Although it's functional we still get warning when dealing with table
FKs that weren't selected together; among others gotchas ;-).

Unfortunately I didn't find any mailing lists or forum to treat this
issue neither at pgfoundry nor autodoc's website.

FKeys still unfixed.
Statistics portion cleaned up by me.
Virtually no testing of input for comma separated values but oh well.

Will follow with a fix to all the "gotchas"
