Thread: Search the schema

I am looking for the ability to search the schema. I'd like to be able to see, for example, where a particular string
occursin a function or a view or table (or perhaps other objects). Right now I am forced to dump the schema and then
searchoutside PgAdmin. <br /><br />So, I guess, I am asking for such a feature to be added to PgAdmin.<br />

pgAdmin 1.16 (right now in beta) gives you the ability to search for
objects' names that contain a specific string. But I guess it doesn't go
as far as you want, does it?

No, it doesn't.<br /><br /> For example, I want to see if a given string is used within a function.<br /> I want to be

That's what he does already.

That won't do it. First time I hear someone needs this.

I do keep the code in a versioning system. And that is a big help. But that doesn't solve the problem of what is actually installed. Searching the schema would be a big help.

I do also :)
Using dump file as workaround.

OK then. I added a ticket to work on this. I already wanted to add
search inside comments, I'll have to work also on source code
(functions, views).

What motivated me to ask for this feature was that I was looking to see if the dependents/dependencies tabs
on function would show all the objects that use the function and the objects that the functions uses, including other functions, views, etc.
Those relationships, I realize, are not explicitly maintained by Postgres, but if PgAdmin could emulate that, it would be great.
But probably hard, so the search was the next best thing.

Given that functions have multiple signatures (same function name with a variable number of args), I'd like to be able to find all the places
that one variant of the function is used. For example if there is a function A with two variants: A(int,int) and A(int, text) -- I'd like to be able to see where
A(int, text) is used.

Hard is not the issue. The dependents/depencies tabs are for
dependencies as given by PostgreSQL. It won't change.

That won't happen. It's too complicated. What I can do is search for a
specific string.  Begin able to check if A(int, int) is used in this
function, but not function A(int, text) means we need to add something
that will understand the PL/pgsql code. I won't work on that. You can if
you want, but I won't.

The idea I want to work on is to search specific string in a source
code, that's all.

Of course, makes sense, which is why I made the feature request I did (ie, search). Would you consider adding regex
expressionsto the search?<br /><br /><div class="gmail_quote">On Thu, Jul 19, 2012 at 3:13 AM, Guillaume Lelarge <span

Well, it wouldn't be hard to do because the search is done by
PostgreSQL. So we can use PostgreSQL regular expressions.
