    <p>I've been making my living working with computers since 1972. In 1980 I founded a consulting company I ran until 2005; during that time I worked with a wide variety of applications, organizations, and technical environments. I'm now with VMware as a PostgreSQL engineer, and tech lead for use of PostgreSQL within their products. I'm a committer for the free, open source version of PostgreSQL, and an active member of that community.</p> <p>By far the largest patch I've worked on for PostgreSQL has been the Serializable Snapshot Isolation (SSI) implementation which went into PostgreSQL version 9.1. This was a joint project with Dan R.K. Ports of MIT, with helpful input and support from many in the PostgreSQL community. Our paper on that effort can be found here:</p> <p><a href="http://vldb.org/pvldb/vol5/p1850_danrkports_vldb2012.pdf" rel="nofollow noreferrer">http://vldb.org/pvldb/vol5/p1850_danrkports_vldb2012.pdf</a></p> <p>For the PostgreSQL docs on the feature, see:</p> <p><a href="http://www.postgresql.org/docs/current/interactive/transaction-iso.html" rel="nofollow noreferrer">http://www.postgresql.org/docs/current/interactive/transaction-iso.html</a></p> <p>For a number of examples see:</p> <p><a href="http://wiki.postgresql.org/wiki/SSI" rel="nofollow noreferrer">http://wiki.postgresql.org/wiki/SSI</a></p> <p>More recently I've added support for creating and refreshing materialized views to PostgreSQL, and am in the process of adding support for incremental maintenance based on the view's declaration.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
