> Hello there. I've just upgraded to pgsql 7.2 on netbsd and one of my programs stopped working because of a parser

You also upgraded in 10 minutes ;)
The release notes explicitly mention syntax changes to support SQL9x
date/time precision features. In particular, "time(p)" is now not
recognized as a function call but rather as a specifier for the type
"time" with a precision of "p". You can rewrite your query using
standard SQL9x syntax (which was also available in versions prior to
7.2):
insert into registros
values (1234,'Teste','A','Teste',date 'now',time 'now',false);
In general, you know and I know that PostgreSQL uses functions of the
form "type(src)" to do type conversions, but it is usually better to use
standard SQL to actually write your queries. The two forms of literal
coersion for a string to a type which SQL9x defines are:
type 'string'
cast('string' as type)
where SQL9x defines the first form as applying to date/time literals
only while PostgreSQL extends this to all data types.
