+/// @file pgsql_query_macros_dhcp.h
+/// Collection of common macros defining PgSQL prepared statements used
+/// to manage Kea DHCP configuration in the database.
+///
+/// Some of the macros are DHCPv4 specific, other are DHCPv6 specific.
+/// Some macros are common for both DHCP server types. The first
+/// parameter @c table_prefix should be set to @c dhcp4 or @c dhcp6,
+/// depending which DHCP server type it relates to. Provided value
+/// is used as a prefix for PgSQL table names. For example, if the
+/// prefix is set to @c dhcp4, the table name referred to in the
+/// query may be dhcp4_subnet etc. The second argument in the variadic
+/// macro is a part of the WHERE clause in the PgSQL query. The fixed
+/// part of the WHERE clause is included in the macro.
