Feature request: option to change default quote style for set_quote_sql_str

[cwells]

The extra "for" parameter causes incompatibilities with other modules, for instance:

array_map_op set_quote_sql_str for=pg $array;

generates an error.

It would be nice if default of MySQL could be changed with directive, e.g.:

set_quote_style pgsql;      ## or set_quote_style mysql
array_map_op set_quote_sql_str $array;

Yeah, I've also fixed it in v0.12. Now we no longer support the for=pg option in the set_quote_sql_str directive, it will always stick to mysql's quoting method. For PostgreSQL literals, we introduce a new set_quote_pgsql_str directive that can be combined with ngx_array's array_map_op, for instance,

array_map_op set_quote_pgsql_str $my_array;

Could you try this out?

Thanks!
