Re: IF (NOT) EXISTS in psql-completion

The new behave is much better.

I found new warning

 tab-complete.c:1438:87: warning: right-hand operand of comma expression has no effect [-Wunused-value]
gcc -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendif-labels -Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -fexcess-precision=standard -g -O2 -I. -I. -I../../../src/interfaces/libpq -I../../../src/include -D_GNU_SOURCE -I/usr/include/libxml2   -c -o sql_help.o sql_help.c

There is small minor issue - I don't know if it is solvable. Autocomplete is working only for "if" keyword. When I am writing "if " or "if " or "if exi" - then autocomplete doesn't work. But this issue is exactly same for other "multi words" completation like  "alter foreign data wrapper". So if it is fixable, then it can be out of scope this patch.

anything else looks well.
