Need help: pgpool-regclass error

[newbie my]

Hi everyone in the listing.

I have a problem when installing the pgpool-regclass.

When I'm running 'Make',it shows me this kind of error :

gcc -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -I/usr/include/et -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendif-labels -Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -fpic -I. -I. -I/usr/pgsql-9.2/include/server -I/usr/pgsql-9.2/include/internal -I/usr/include/et -D_GNU_SOURCE -I/usr/include/libxml2  -I/usr/include  -c -o pgpool-regclass.o pgpool-regclass.c

pgpool-regclass.c:99:37: error: macro "RangeVarGetRelid" requires 3 arguments, but only 2 given

pgpool-regclass.c: In function âpgpool_regclassâ:

pgpool-regclass.c:99: error: âRangeVarGetRelidâ undeclared (first use in this function)

pgpool-regclass.c:99: error: (Each undeclared identifier is reported only once

pgpool-regclass.c:99: error: for each function it appears in.)

make: *** [pgpool-regclass.o] Error 1

Can anyone help me to sort this things out?I really appreciate it.

Thanks.

Best regards,

Alqaf
