You may want to look at this:
http://www.postgresql.org/docs/view.php?version=7.3&idoc=0&file=features.html

"Appendix C. SQL Conformance"

especially:
"SQL92 defined three feature sets for conformance: Entry, Intermediate, and
Full. Most database products claiming SQL standard conformance were
conforming at only the Entry level, since the entire set of features in the
Intermediate and Full levels was either too voluminous or in conflict with
legacy behaviors."

which I would translate to "there is no such thing as a 100% SQL-92
compliant database". I may be wrong; maybe someone with more
detailed knowledge of the standards can correct me.

The same page also has a detailed list of supported and unsupported
features from SQL 99. While a large number are not implemented in
PostgreSQL I would suggest its price / conformance relationship is
excellent.
