Here is a tar file the new directories, which substitute the old ones
in contrib. Please remove the old directories array, datetime, miscutil,
string and userlock before unpacking the tar file in contrib.

Note that as the modules are now installed in lib/modules I install all
my sql code in lib/sql. In my opinion also the other contributors should
follow these rules.

  This patch fix the Makefiles in contrib/{pginterface, spi,
miscutil, int8, ip_and_mac, sequence, soundex, string, userlock,
array, datetime} to install their modules in one directory(lib/modules/).

Change some labels in bootparse to make ctags happy.  Clean up outfunc/readfunc code and add missing fields for Query structure and new Union fields.  Fix optimizer bug shown in new \do command.  Change WARN to ERROR in contrib and regression stuff.

Another PGINDENT run that changes variable indenting and case label indenting.  Also static variable indenting.
