If you don't care about multi-database compatibility, consider storing your data as TEXT and add a constraint to limits its length. VARCHAR is a terrible type that exists in PostgreSQL only to comply with its associated terrible part of the SQL standard. You'll need to figure out how to truncate those manually-so you're back some locks just on oversize ones-because if someone tries to update anything on that row it's going to reject it as too big now, at the point it goes to store the new version of the row. You would be wise to do a scan over the whole table looking for rows where the length of the field is >40 characters after making the change. If you hack a lower limit in there, that will not reduce the size of existing values at all. The length check is done when values are stored into the rows. ![]() All sorts of weird cases to be aware of here. Make sure you read the Character Types section of the docs before changing this. The only way to do this officially is with ALTER TABLE, and as you've noted that change will lock and rewrite the entire table while it's running. You have to hack the database catalog data. If you choose a replacement font for the document, then later install the missing font, your document continues to use the replacement font until you replace it with the font you installed.There's a description of how to do this at Resize a column in a PostgreSQL table without changing data. If you have the missing font and want to install it on your computer, use Font Book, available in the Applications folder on your Mac (see the Font Book User Guide for instructions). In the notification, click Show and choose a replacement font. When you open a document that uses fonts not installed on your computer, a missing font notification appears briefly at the top of the document. The replacement font uses the same size and weight as the font it replaces. The font is replaced everywhere it occurs. If the font is listed as a missing font, also choose a typeface. To change a font everywhere it occurs in your document, you can replace it with another font.Ĭhoose Format > Font > Replace Fonts (from the Format menu at the top of the screen).Ĭlick the double arrows to the right of the font you want to replace, then choose a replacement.
