# CREATED BY Tatsuo Ishii 1998/7/22
# CONTAINS: Set of tests for multibyte supporting extentions for PostgreSQL. 
# LAST UPDATE BY Ayush Parashar 2005/July/7
# ENHANCEMENTS:
#   1. - Include extensive multi-byte regression tests for copy command.
#      - Uses following complete character sets and encoding types for testing: 
#        "big5 gbk uhc gb18030 euc_cn latin8 iso_8859_6 iso_8859_7 euc_kr euc_jp" 
#   2. Include help and usage for various tests.
#   3. Include cleanup function, to remove the log files and database objects that have been created.
# REQUIREMENTS:
#  - Installed PostgreSQL
#  - The location of bin directory of PostgreSQL should be included in "PATH" variable.
