you would pass the SQL statements to do what you want to the various
libpq library functions...
something like...
PGconn *conn;
PGresult *res;
conn = PQconnectdb("dbname=mydatabase");
if (PQstatus(conn) != CONNECTION_OK) {
fprintf(stderr, "Connection to database failed: %s",
PQerrorMessage(conn));
exit_nicely(conn);
}
res = PQexec(conn, "create table test (id serial, num int, value
text);");
if (PQresultStatus(res) != PGRES_COMMAND_OK) {
fprintf(stderr, "BEGIN command failed: %s", PQerrorMessage(conn));
PQclear(res);
exit_nicely(conn);
}
...
most folks would probably put the PQexec() and status tests into a
function to simplify things.
