Обсуждение: strange error

I don't know if this mailing list is the appropriate ML, but:
I think that in postgresql 6.3.2 there is a little bug.
I have a table. I exec:
alter table my_table add column mycolumn mytype\g
now if I make a select on this new column I get this error

ERROR:  RestrictionClauseSelectivity: bad value 2.350645

Otherwise, if I drop the my_table and recreate my_table with the new
column all
is work. Why this ?

And again another question. I drop my_table. I re-create my_Table with
this comm
and:
www=> create table sito (url varchar(255) PRIMARY KEY,
www-> titolo varchar(255), note varchar(64), indicazioni varchar(50),
genere int
,visto int, titolo_down varchar(255));\g

and psql return me:
NOTICE:  CREATE TABLE/PRIMARY KEY will create implicit index sito_pkey for
table
 sito
CREATE
NOTICE:  CREATE TABLE/PRIMARY KEY will create implicit index sito_pkey for
table
 sito
ERROR:  amcreate: sito relation already exists

why the error?

tnx

Somehow the analyze statistics has goteen out of wack.  Do a VACUUM
ANALYZE on the table, and the problem will go away.  If can reproduce
the problem, please send the information to the hackers list.  Thanks.
