Subject: [PATCHES] INSTALL changes

This patch modifies the INSTALL file.  The changes are:
  - SPARC/Linux-ELF was added to the list of supported platforms.
    The special notes for it at the bottom of the file were removed.
  - Changed "database server" to "RDBMS database server".
  - Modified step 6 so that when you restore your database the
    tables will be owned by the original owners instead of the
    postgresql superuser.
  - Modified step 19 on diagnosing the regression tests for the
    SPARC Linux platform with a beta release.
  - Other minor changes.
