Well, you don't seem to have specified any files to link.  The second
cc command says to create an executable called `.c' but doesn't specify
and files to compile or link, except the libpq library.  So naturally, cc
cannot find a main() routine; that is what it is complaining about.

Ah, I see it's not your fault but the Makefile's...

I guess you are using GNU make, as I am.  This works for me:

=======================================================
#
# Makefile for GNU make
#
#
PGINTERFACE = pginterface.o halt.o
TARGET = pginsert pgwordcount pgnulltest
CFLAGS = -g -Wall -I/usr/local/pgsql/include -I.
LDFLAGS = -L/usr/local/pgsql/lib -lpq

all : $(TARGET)

$(TARGET): %:   %.o ${PGINTERFACE}
        $(CC) -o $@ $(CFLAGS) $@.c ${PGINTERFACE} $(LDFLAGS)

clean:
        rm -f *.o $(TARGET) log core

install:
        make clean
        make CFLAGS=-O
        install -s -o bin -g bin $(TARGET) /usr/local/bin
=======================================================
