We are announcing the start of PostgreSQL ecosystem survey. By filling out the following survey form, please let us know what software you need in order to adopt PostgreSQL in wider range. The form comprises three questions: software/usage/industry category, a specific software, and a free comment on the interoperability issue of the software. Your request will encourage us to improve the interoperability of PostgreSQL to make more software available with PostgreSQL.

Survey form

You can see the survey result in real time in the spreadsheets below.

We really appreciate your cooperation. Thanks.

Community discussion


Thanks to the long and hard effort by the community, PostgreSQL has been evolving to be a really great software comparable to existing strong commercial products. According to the following article, open source databases are gaining more popularity enough to influence the database market.

Open source threatens to eat the database market

"Though the proprietary RDBMS market grew at a sluggish 5.4 percent in 2014, the open source database market grew 31 percent to hit $562 million."
"As Gartner highlights in a recent research report, open source databases now consume 25 percent of relational database usage."

On the other hand, there is a gulf between the two top popular databases -- Oracle and MySQL -- and PostgreSQL. They are nearly five times more popular than PostgreSQL.

DB-Engines Ranking

Yes, I understand this ranking doesn't necessarily reflect the actual use, but I also don't think the ranking is far from the real popularity.


What will be necessary for more users to use PostgreSQL? One challenge is interoperability, or ecosystem in other words, which is to increase the number of software which supports PostgreSQL. To take advantage of the trend of shift from commercial products to open source, PostgreSQL needs to interoperate with many software that are used together with the commercial databases.

The easily understandable target is Oracle, because it is anticipated that more users of Oracle will seek another database to avoid the expensive Oracle Standard Edition 2 and increasing maintenance costs. In addition, PostgreSQL has affinity for Oracle.

However, there is a problem. The number of software is very small that the users can know to interoperate with PostgreSQL. That is, when the users want to migrate from commercial databases to PostgreSQL, they can't get information on whether they can continue to use their assets with PostgreSQL. Many applications might be interoperable through standard interfaces like JDBC/ODBC, but the case is unknown. For example:

* Only 24 open source projects are listed as interoperable.
Open Source Projects Using PostgreSQL

* About 120 products are listed in the "Software Catalog" (excluding the ones like PostgreSQL extensions). But the number would drop down to about 100 if the members of the same product family are counted as one.

* Even EnterpriseDB has only 12 certified application vendors.

* PostgreSQL Enterprise Consortium lists only about30 related products (Japanese only).

* MySQL touts more than 2,000 ISV/OEM/VARs.

Besides, in practice, more development efforts will probably be necessary to make PostgreSQL more interoperable with many software products. For example, one customer asked me whether Arcserve can be used to back up PostgreSQL databases, but unfortunately I had to answer no.


At the steering committee of PostgreSQL Enterprise Consortium (PGECons), I proposed starting the following activity. PGECons is a Japanese non-profit organization to promote PostgreSQL for enterprise use. The members include NTT, SRA OSS, Inc. (Tatsuo Ishii runs), NEC, Hitachi, HP, Fujitsu (my company), etc. The committee concluded that we need to work in cooperation with the PostgreSQL community.

* Attract and ask product/service vendors to support/use PostgreSQL. Provide technical assistance to those vendors as an organization so that they can support PostgreSQL smoothly. If the vendors aren't proactive, we verify the interoperability with their software by executing it.

* Make a directory of software/services that can be used with PostgreSQL on the community web site ( or Software/services vendors and PostgreSQL developers/users can edit this directory. This list not only has the names of software and its vendors, but also other information such as the level of interoperability (certified by the vendor, or verified by the community/users) and remarks about configuration, tuning, and whatever useful for users.
