User visible changes in pgscsh

* News in version 0.4

** Experimental support for Scheme48 1.5

The only currently available authentication mode is "password".

Contact me if you really need to make this library work with previous
versions of Scheme 48.

** INCOMPATIBLE CHANGE: updated date/time parsers

The data types "timestamp", "time" and "date" (the first two both with
and without time zone) are returned as SRFI-19 date objects.  In
previous versions Scsh date records were used.

The data types "abstime", "reltime", "datetime" and "timespan" are
considered deprecated as of version 7.3 of PostgreSQL and are returned
unparsed, as strings.

The data type "interval" is returned unparsed as a string.

* News in version 0.3

** Automatic installation through Michel Schinz's Installation Library

** Added support for "crypt" authentication

** Added support for MD5 authentication

** Basic support for transactions

The form

   (pg:with-transaction* connection thunk)

executes THUNK within a transaction in CONNECTION.

The syntactic form

   (pg:with-transaction connection body ...)

is syntactic sugar for

   (pg:with-transaction* CONNECTION (lambda () BODY ...))
