Обсуждение: Update hstore % Doc

Hackers,

I noticed that the hstore docs still document the => operator instead of %. This patch changes that. It also updates
thefirst examples to us full SQL statements, because otherwise the use of => without surrounding single quotes was
confusing.

Best,

David

It looks to me like you are changing the examples of the I/O
representation ... which did NOT change.

Hrm? The first few examples at the top? I find them confusing because there are no single quotes around them, so they
looklike the use of the deprecated => operator (especially the first two). Just look at:  
http://developer.postgresql.org/pgdocs/postgres/hstore.html

Maybe that's standard in the docs, but it seems weird to me. It's a minor point, though.

We definitely need to document the `text % text` constructor rather than the deprecated `text => text` constructor.

And I hate to say it, but % is awful. Sorry, I know I'm probably opening a can of worms here, and I did finally push %
afterall the arguments, but coming back to it fresh it just looks bizarre to me. Maybe that ship has sailed, though,
andI'm just being difficult. 

Best,

David

Yeah, but there's a sentence in front of them that says specifically
that these are examples of the text representation, not pieces of SQL.

Yeah, I know, but you can't have =>.  Unless you can persuade the SQL
committee to back off their syntax choice for parameters.  (:= would
have been a lot better ...)

BTW, there isn't any % constructor anymore --- we agreed to provide
only the hstore(text, text) constructor.

Oh, I must've been looking at an older checkout, then. Never mind.

And also - it was never the constructor.  It was briefly the slice operator.
