oops after I took out functions marked for deprecation in r17029, ran into this issue.

[robe]

In 17030:

Put back deprecated functions removed in r17029, but patch them to use newer pg_get_constraintdef function.
Also mark them as undeprecated cause they are used in other management functions, and it's too messy to change those to use teh raw sql.
We maybe stuck with these forever
Closes #4243 for PostGIS 3.0

Also fix error in raster patching
