Some minor comments here:

v35-0001 - logicaldecoding.sgml

In the example section:
Change "The following example shows SQL interface can be used to
decode prepared  transactions."
to "The following example shows the SQL interface that can be used to
decode prepared transactions."

Then in "Two-phase commit support for Logical Decoding" page:
Change "To support streaming of two-phase commands, an output plugin
needs to provide the additional callbacks."
to "To support streaming of two-phase commands, an output plugin needs
to provide additional callbacks."

Other than that, I have no more comments.
