2000-02-08：更新 to_char() 函数。
25 年前的今天（PostgreSQL 7.0 开发周期），对 to_char() 函数的一次更新被提交
commit 394af52795f6bb02ae26af2ddca6cec0f255ee33 Author: Bruce Momjian <bruce@momjian.us> Date: Tue Feb 8 15:57:01 2000 +0000 I'm sending patch with new version of to_char numbers formatting. The PostgreSQL's to_char() is very compatible with Oracle's to_char now. I hope that to_char's 3000 rows of source is without bugs, but will good if anyone test it, for me it works very well :-)
这次更新为几天前添加的 to_char() 函数添加了一些修正、代码清理和小型改进（几天前）。
