Subject: Fix bug which does not rewrite timestamp.
X-Git-Tag: V3_1_0_ALPHA3~17
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=26be6efc7844d10c33aca8ed4f70c6ae5d366630;p=pgpool2.git

Fix bug which does not rewrite timestamp.
Fix rewrite_timestamp_walker so that it can process 2 cell list.
This used to work but was broken in 3.1.0 alpha2 using 9.0 parser.

Change history of functions to create lists in gram.y:
                SystemFuncName()  SystemTypeName()
8.1.3 original  list_make2()      list_make2()
8.1 import      list_make1()      list_make1()
8.3 import      list_make1()      list_make1()
8.4 import      list_make1()      list_make2()
9.0 import      list_make2()      list_make2()
