in DecodeTimeOnly(). Only present when seconds are not specified
 for input.

Rename date+time conversion to datetime to ensure less than 16 characters
 in routine name (required to fit in pg_proc table).

Before, char16 was missing last character for output.

Allow true/false, yes/no, 1/0. Throw elog warning if anything else.
Allow shorter strings, so "t", "tr", "tru" and "true" match "true".
Old behavior accepted anything starting with "t" as TRUE,
 everything else as FALSE.

Leave all other input values to return FALSE.
In next version, do more checking for valid inputs for both TRUE and FALSE.

Allows the following example:
  select 'first string'
  '---'
  'last string';
 to be output as 'first string---last string'.

RelationIdCacheGetRelation() to flush relations from cache
in commit time.

 rather than just 't' and 'T'.  This allows yes/no and 1/0
 to be interpreted as one might expect.
Clean up function declarations to use bool as the type for arguments
 and return values.

lconv is already taken as a struct identifier defined in a /usr/include file.
Only has an effect with USE_LOCALE enabled.
(Apparently unique to AIX and/or AIX compiler? thomas)

Should be changed for v6.3!

 Polygon input would not accept single-point polygon output and dump.

clauses.

Add SQL/92 types decimal and numeric (temporary for syntax support).
 These types need more support in the backend to be really implemented,
 and the parser will need to be changed at that time.
Adjust limits on precision parameters for FLOAT(p) to match IEEE-compliant
 arithmetic. Perhaps these limits should be processor-specific or obtained
 from system include files instead.

Add SQL/92 "constants" current_date, current_time, and current_timestamp.

 like newline inside quoted strings.
