Is it possible to do variable substitution with explicit locks in plpgsql? Something along the lines of
...
declare
big_string alias for $1;
excl_table text;
begin
--assuming big_string starts with something like table=table1!
excl_table := substr(big_string,7,(position(''!'' in big_string)-7));
lock table excl_table in exclusive mode;
...
Thanks very much.
