By permanent code, I meant code that runs every time, instead of asking
the phpMyAdmin installer to run a conversion script.

Yes, I understood that, what I meant was whether there will be some

if-else sections that treat either the old format in pma_column_info

( x_y__t.inc.php ), either the new one ( x_y_t.class.php )?

And if so, this leads to the next question.

We are not responsible for code changes in phpMyAdmin.

(I am sorry again for the misunderstanding) I meant if the user

has a table that contains old transformations on columns, and

he tries to modify that, what happens? If he has transformation 1

(x_y__transf1.inc.php) and wants to switch to transformation 2,

will that become x_y__transf2.inc.php or transf2-neutral-string

in his pma_column_info table?

To summarize, if we choose the permanent code version, will

that imply treating both cases and leaving the pma_column_info

unchanged for the users that have the old format? Otherwise,

they will have a mixture of old and new transformation entries.

The only way I see to change them all without a script, would

be to run a full update (for all of the entries) on their column_info

table every time (hopefully only the first) an old format

transformation is found and replace it with the new neutral string.
