Regarding patch d.
+ /* compute total_weight */
+ for (i = 0; i < num_scripts; i++)
+ total_weight += sql_script[i].weight;
total_weight can overflow :) I don't think that's worth worrying, I am
just noticing that.

- if (strncmp(builtin_script[i].name, name,
- strlen(builtin_script[i].name)) == 0)
+ if (strncmp(builtin_script[i].name, name, len) == 0)
I agree with Alvaro here: this should remain unchanged. It seems to be
a rebase mistake.
