可能吗？我想设置两个不同的目录来提供静态文件.让我们说/ public和/ mnt

我有2个Ruby版本:1.8.7和1.9.2以及PostgreSQL 8.3.我不能在任何一个上安装pg gem.得到此错误:

C:/Development/Ruby187/bin/ruby.exe extconf.rb
checking for pg_config... yes
not recorded
checking for libpq-fe.h... no
Can't find the 'libpq-fe.h header
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:
 --with-opt-dir
 --without-opt-dir
 --with-opt-include
 --without-opt-include=${opt-dir}/include
 --with-opt-lib
 --without-opt-lib=${opt-dir}/lib
 --with-make-prog
 --without-make-prog
 --srcdir=.
 --curdir
 --ruby=C:/Development/Ruby187/bin/ruby
 --with-pg
 --without-pg
 --with-pg-config
 --without-pg-config
 --with-pg-dir
 --without-pg-dir
 --with-pg-include
 --without-pg-include=${pg-dir}/include
 --with-pg-lib
 --without-pg-lib=${pg-dir}/lib

我知道这是一个常见的问题,但我还没有找到任何有效的解决方案...哦,我已经将C:\ Program Files(x86)\ PostgreSQL\8.3\bin添加到我的PATH中.

我是Postgres的新手,我不知道如何将这个MySQL查询翻译成postgres:

SELECT pictures.id, MATCH (title, cached_tag_list) AGAINST ('phrase') AS score FROM pictures WHERE MATCH (title, cached_tag_list) AGAINST ('phrase') ORDER BY score DESC;
