+Title: Database Validation and Versioning
+
+Abstract:
+
+There are many advantages to maintaining full build scripts for your database.  They allow you to create your database from scratch, run unit tests, and serve as a useful reference to the current state of the database.  However, in production full build scripts are only run once per database.  After that it is an endless sequence of update scripts.  How do you to keep the full build and update scripts in sync?  How can you be sure that your production database looks exactly like your full build once all the updates have been applied?  In this talk we’ll examine how validation and versioning can be used to ensure that production databases always match full builds even after thousands of updates have been applied.  There will be practical demonstrations using tools such as check_postgres and sqitch.

+comparison/diffing of database schemas. You can find more information at its
+website at http://apgdiff.startnet.biz/
+
+## Changelog
+
+### 2012-09-21: Version 2.4
+
+#### New Features
+* Added support for ALTER SEQUENCE OWNED BY (patch by Mikhail Petrov).
+* Added support for CREATE TRIGGER ... UPDATE OF column.
+* Added switch --ignore-slony-triggers which causes that Slony triggers
+  _slony_logtrigger and _slony_denyaccess are completely ignored during parsing
+  and diffing.
+
+#### Fixes
+* Fixed issue with comments not being added on newly created columns.
+* Improved logging errors when parsing strings.
+* Added support for IF NOT EXISTS (patch by Felipe Sateler).
+* Fixed NPE when search_path contains quoted schema (patch by Steven Elliott).
+* Fixed dropping of default values when --add-defaults is specified (patch by
+  Jim Mlodgenski).
+* Fixed all bugs related to incorrect parsing of end of statement, most often
+  resulting in StringIndexOutOfBoundException.
+* Fixed CREATE TABLE statement output when table contains no column.
+
+### 2010-10-22: Version 2.3
+
+#### New Features
+* Added support for diffing of COMMENT ON statements.
+* Added switch --list-charsets to output list of supported charsets.
+
+#### Fixes
+* Added user error messages instead of NullPointerException for cases when
+  referenced database object was not found in the dump.
+* Fixed bug with parsing quoted object name when both first and second part of
+  the name was quoted.
+* Fixed bug in parser that caused in some cases invalid match against expected
+  "word".
+* Fixed bug in parser that caused array data types not detected correctly (was
+  caused by fix of invalid match of "word" above).
+* Functions are now created after tables are create and updated, because of
+  functions depending on tables and columns. Later will be implemented solution
+  for cases where functions have to be created before table columns.
+
+### 2010-10-09: Version 2.2.2
+
+#### Fixes
+* Added missing new line after ALTER VIEW ... ALTER COLUMN ... SET/DROP DEFAULT.
+* Fixed parsing of quoted string values.
+* Fixed detection of function body separator (did not work when there was
+  another 'AS' specified on the same line after the 'AS' starting function
+  body).
+* If two dumps are completely same and there is more than one schema in the
+  dumps, the output now does not contain 'SET search_path = ...'. In other
+  words, if two dumps are completely same, no output is produced.
+* Replaced 'ALTER VIEW name ALTER COLUMN ...' with 'ALTER TABLE view_name ALTER
+  COLUMN ...' to make it compatible with PostgreSQL releases prior to 8.4.
+* Fixed parsing of '' escapes.
+
+#### Other
+* Added support for localization of apgdiff.
+* Added Czech localization.
+
+### 2010-10-03: Version 2.2.1
+
+#### New Features
+* Commands like OWNER TO and ENABLE/DISABLE TRIGGER/RULE are now added to the
+  diff output even for commands that are otherwise being parsed, like ALTER
+  TABLE.
+
+#### Fixes
+* Fixed bug where default values were dropped from VIEW columns even if they
+  were not modified.
+
+### 2010-10-02: Version 2.2
+
+#### New Features
+* Statements that are not supported by apgdiff yet are now all ignored(till this
+  release apgdiff had to be instructed to know what commands to ignore which was
+  not good solution). This is the same behavior as in 1.* releases.
+* Added command line switch <code>--output-ignored-statements</code> which can
+  be used to output statements that apgdiff ignores in the dump files. This
+  feature makes more clear what statements were ignored and developer has to
+  handle them manually eventually.
+
+### 2010-09-30: Version 2.1
+
+#### New Features
+* Added support for ALTER VIEW.
+* Added support for ALTER TABLE view_name/sequence_name.
+
+#### Fixes
+* Fixed issue with comparison of VIEWs when columns are not specified but query
+  has changed.
+* Fixed parsing of quoted names at many places.
+* CREATE RULE is now silently skipped.
+
+### 2010-09-16: Version 2.0.2
+
+#### Fixes
+* CREATE DOMAIN is now silently skipped.
+
+### 2010-09-16: Version 2.0.1
+
+#### Fixes
+* CREATE OPERATOR and ALTER LANGUAGE are now silently skipped.
+
+### 2010-09-13: Version 2.0 Including Beta Releases
+
+#### New Features
+* SQL parser has been completely rewritten to allow safer and more flexible
+  parsing of SQL statements.
+* Statements not supported by apgdiff are now not silenty ignored if apgdiff is
+  not told (by me in code) to ignore them.
+* Added support for ALTER TABLE ... ALTER COLUMN ... SET STORAGE
+  PLAIN|EXTERNAL|EXTENDED|MAIN.
+* Added support for CREATE TABLE ... TABLESPACE.
+* Updated parsing of CREATE TABLE ... WITH/WITHOUT OIDS.
+* Added support for CREATE TRIGGER ... WHEN and for even TRUNCATE.
+* Added support for CREATE SEQUENCE ... OWNED BY.
+* CREATE SCHEMA is now supported for both syntaxes.
+* Added support for default values on function arguments.
+* Added support for parsing ALTER TABLE ... ENABLE/DISABLE TRIGGER/PARSER, but
+  they are not diffed for now.
+
+#### Fixes
+* ALTER SEQUENCE and CREATE AGGREGATE are now silently skipped.
+* Fixed parsing of end of function.
+* Improved handling of dotted quoted names.
+* Fixed quoting of SQL reserved keywords.
+* Fixed parsing of function arguments.
+* Triggers are now dropped before functions are dropped (bug #2991245).
+* Improved diffing of CREATE TABLE ... INHERITS.
