I prefer existing names because your new default behavior can be done with suitable nullstr values. IMHO, new names will be acceptable only if they are listed in the SQL-standard or many other databases use the names. Two similar versions of functions must confuse users. Also, are there any consensus about "existing functions are not correct" ? Since string_agg() and your new concat() functions ignores NULLs, I think it is not so bad for array_to_string() to ignore NULLs. -- Itagaki Takahiro -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
