there's a paragraph in the ALTER TABLE reference page that reads:

DROP CONSTRAINT

    This form drops constraints on a table. Currently, constraints on tables
    are not required to have unique names, so there may be more than one
    constraint matching the specified name. All matching constraints will be
    dropped.

To my knowledge, it is no longer possible to create constraints with the
same name for the same relation. When you create a constraint and specify
the same name explictly, an error is raised. Implicit constraint creation
won't choose an existing name either and up to now you could not rename a
constraint. Renaming works with the patch I sent in a few hours ago but this

relation.

This is used by winsock2.h. However, Construction of a windows base is
winsock.h.
Then, Since MinGW has special environment, this is right. but, it is not
found in VC6.
Furthermore, in getaddrinfo.c, IPV6-API is used by
LoadLibraryA("ws2_32");
Referring to of dll the external memory generates this violation by VC6
specification.

I considered whether the whole should have been converted into winsock2.
However, Now, DLL of MinGW creation operates wonderfully as it is.
That's right, it has pliability by replacement of simple DLL.
Then, I propose the system using winsock(non IPV6) in construction of
VC6.

Treat procedural languages as owned by the bootstrap superuser, rather

intervals, rather than bypass and print the full interval hours.  This
