Yep. Applying the pgindent is kind-of a pain, so I tend to do a reasonable 
job by hand and rely on the next global pgindent to fix such things. I 
shorten the line anyway.

It could, but it would mean switching to using a format which is not very 
useful here as it uses the simpler append*Str variant.

While looking at it, I noticed the repeated tablespace addition just 
afterwards, so I factored it out as well in a function.

Attached v3 shorten some lines and adds "append_tablespace".
